Tonight on
The Curse of Oak Island...

Everything that we dug up

led us to this area
being the Money Pit.

We just need to find
the right spot at depth.

If it's there,
we should find it.

Fiona?
It was shining in the sun.

Hallelujah.

Oh, is that it? [laughs] Oh!

- Here we go.
- What do we got?

Fits in with
the time period of 1600s.

It's probably the coolest thing

- that I've looked at.
- Really?

Valuation? Sky's the limit.

- Oh, my gosh.
- Yeah.

There is an island
in the North Atlantic

where people
have been looking for

an incredible treasure
for more than 200 years.

So far, they have found
a stone slab

with strange symbols
carved into it,

man-made workings
that date to medieval times,

and a lead cross
whose origin may be connected

to the Knights Templar.

To date, six men have died

trying to solve the mystery.

And according to legend,
one more will have to die

before the treasure
can be found.

We came in with
a purpose this year,

and the purpose was
to put every borehole

on the bottom
of the solution channel.

Yeah, absolutely.

As a new day
begins on Oak Island,

brothers Rick and Marty Lagina

and their team are
energized by the belief

that they could
finally be on track

to solve a 230-year-old
treasure mystery.

Everything that we dug up

led us to this area
being the Money Pit.

We just need to find
the right spot at depth,

- beneath 150 feet.
- Yeah.

Whatever was put

in the Money Pit fell

to where it could fall no more,

i.e., the solution channel. So,

if it's there,
we should find it.

Yeah, time's gonna tell.

The team is
currently drilling a borehole

in the fabled
Money Pit area known as J-9.

A borehole located where
they believe the original

treasure shaft,
first discovered in 1795,

has collapsed after
more than two centuries

of repeated excavations
and fallen into a massive,

natural cavity in the bedrock
known as the solution channel

between 150
and 220 feet underground.

We're looking for
what, hopefully, Pitblado found

in 1849.

After the collapse,
I think it's all down there.

- The whole thing is down there.
- Right. Exactly.

Yeah.

This was a coin
that was given to me

that, from my own
research, I believe

is from about 1367.

- Wow.
- One week ago,

the team was presented
with a 14th-century

silver Portuguese coin,

believed to be related
to the Portuguese sect

of the Knights Templar
known as the Knights of Christ.

According to the coin's
current owner, Steve Salomon,

it was recovered during

a drilling operation in 1849

from nearly 100 feet deep in
the Money Pit by James Pitblado,

a drilling foreman who kept
the discovery a secret.

We got a core, gentleman.

Looks like. Yeah.

Get another bag.

Now, having

already detected
high-trace evidence

of precious metals in water deep

underground, they are hoping
to prove that the coin

is genuine by finding many more
in the solution channel.

- What have you got, Kyle?
- 158.

- 158?
- Yeah.

Let's see what we got.

None of the previous
work got to the bottom

of the solution channel,

where a treasure fallen
to those depths could hide.

And what do we got here?

There could be a lot more

coins hiding in there.

I think there are
ample opportunities here

to find out.

These are chunks of limestone.

- Nothing yet, Charles.
- Nothing yet.

What's your suspected depth

of the bottom of
the solution channel here?

In this area?

It's in between 210, 215.

Well, the key would be

to find any evidence
of treasure.

That's your target.

Turn immediately to recovery

and that would
probably mean a big dig.

- Let's find it.
- We're still a ways away,

so call me
if you find anything.

Oh, absolutely.
You're my first call.

Gonna keep our eyes peeled.

As the core drilling
operation continues

in the Money Pit area...

...nearly half a mile
away on Lot 5...

All right, guys.

We're gonna go around
the ferns down to the beach.

...Marty Lagina,
his nephew Peter Fornetti

and metal detection
expert Katya Drayton

search for clues between
a mysterious rectangular feature

and a rounded stone
foundation near the shoreline.

Proceed.

After the surprising discovery

of these two buried
features back in 2022,

the team has made
astonishing finds that suggest

both may have been used

as campsites by different groups

over a number of centuries

prior to the discovery
of the Money Pit.

These finds
include a lead barter token

that, just like the
14th-century lead cross

discovered at Smith's Cove,
may be related

to the Knights Templar.

Another curious clue
is a mortar-like material

that has been found
in both features,

which has been scientifically
matched to soil samples

collected from
more than 100 feet deep

in the Money Pit area.

Oh, there we go.

- It's a two-way signal.
- Okay.

- Sounds good.
- Pete.

This occupation
we know occurred, potentially,

through several time periods.

Amongst other things, we have

direct connection between
Lot 5 and The Money Pit already.

Lot 5 could give us clues
as to when, and by who,

the treasure itself
might have been deposited,

so that could be
very meaningful.

That's a rock.

That's a rock.
How big is it?

Ah, that's a big rock.

Oh, that's a big boulder.

You know what?

There is a pry bar

left from an earlier job
right over here.

Let's see if
we can move this bad boy.

- What you want?
- Put it longways, right there.

This is vaguely reminiscent
of being ten years old again.

Here we are,

with the lowest
of low tech possible.

We got a great big boulder,
we have no hydraulic equipment.

We have a prybar.

We're gonna try
to move this boulder

out of the way, it needs
to get out of the way,

we need to know what's under it.

I'm gonna fall on my face,
is what I'm gonna do.

Wish me luck.

Come on, you big bugger.

This rock here refuses

to be moved.

There have been a lot
of great finds around Lot 5.

And so, it's very
important to get it.

It could be, I mean,
it could be a gold coin.

It could be a coin
with a date on it.

I can't just let that go.

I don't think
we have the right equipment.

I think the skid steer
will fit in here.

- Pete, yes?
- Yeah.

Okay, well, I will go get

the machine and
we'll roll it out of there.

- Awesome. Let's move on.
- Okay.

While Marty retrieves

a small excavator to move
the boulder on Lot 5...

Whenever I see
iron on the table,

I'm excited, obviously.

This could be an important find.

...Rick Lagina
and other members

of the team meet
with Laird Niven

and Emma Culligan in the lab.

It came out of H.5-8.5,

which is 174 to 178 feet deep.

It looked very much
like somebody's

drill casing,
something from before us.

They are about
to hear a scientific report

on pieces of
a believed drill rod

that was recovered
over one week ago,

just feet away
from where they are

currently exploring
in the Money Pit area.

If it was somebody's
old drill steel,

that tells us that
somebody else was interested

in this area
for reasons we don't know.

- Yeah.
- And Emma,

- that's where you come in.
- Yeah.

Earlier this morning,
Emma scanned the metal pieces

using the X-ray
fluorescence spectrometer,

or XRF, a device that can
identify the elements

in an object's composition
to help determine

when it was created.

So, the two metals
are exactly the same thing,

which you

kind of see
just from the look of it

that they belong
to the same piece.

Based on the list of impurities,

its manganese content, I would

put this around
mid-1800s to late 1800s.

The dates that Emma

is relating to us
indicates searcher.

- Mm-hmm.
- The Truro company

in 1849--
they were doing their drilling,

and they brought up the coin

that Pitblado put in his pocket.

In 1849,
members of the Truro Company

excavated the original Money Pit

down to a depth
of nearly 90 feet.

After building a wooden platform

at a depth of 30 feet
in the pit,

they began a drilling operation.

At approximately 100 feet,
they reportedly struck

two stacked chests,
which they failed to recover

due to catastrophic flooding.

However, the company's foreman,

named James Pitblado,
is believed

to have recovered
the 14th-century silver

Portuguese coin from
the end of the drill bit.

They were drilling
when they knew

where the Money Pit was,
so my hope is we're gonna

find more of those
Portuguese coins

- in this area.
- That'd be pretty cool.

Yeah, and we know
the Truro Company

didn't get below any more than
117 feet with their drilling,

so the great collapse

could have carried
this metal down deeper

than any known work at the time.

And that area
of the solution channel

could prove really interesting.

If this steel
correlates to the efforts

by the Truro company

to try to find treasure,
that's important

because it would mean
that we are in the same area

that they were in when
they were looking for the vault,

and we have a coin
that we suspect

might be associated with that,

and it is in this area.

Bottom line is we have
an area that we've

designated an area
of significant interest,

and this supports that.

Given the evidence on the table,

we should redouble our efforts.

- Let's go do it.
- All right.

This could turn into loose,

watery material
within a foot or two, right?

Yep.

While the drilling
operation proceeds

in the Money Pit...

I'm just gonna
try and get right in there

and pluck it out.

And then we're
done with that rock. Yeah.

...Marty Lagina
arrives back on Lot 5

with a small excavator

known as a skid steer...

...to move the boulder
that is covering

what may be an important clue.

The plan to
move the rock initially

was to try and move
it with levers.

Didn't work.

So, then it's time
to bring in the power

of a skid steer.

Oh!

Nothing I like better.

It's kind of hard to move
a rock that's in a hole.

There we go.

But we want to get this out

because it could be
super significant.

And it could be very, very old.

- Okay.
- The rock is moved.

- It is accomplished.
- Finally.

Well, is there
anything in there?

Let's find out.

Please be something in there.

It's so low of a signal,

and it's reading
very low content.

I believe there
was something here...

- Mm-hmm.
- but not anymore.

- It disintegrated. Yeah.
- Yeah.

It seems that it's

a bit of a ghost
we were chasing.

Probably, there was
something in there

that corroded a long time ago.

So, it's still
a bit of a mystery.

We had to do this.

There was a clue,
potentially, under that rock,

and it would have driven
all of us crazy

if we didn't find out.
But we're not gonna let

the island beat us, so let's
get on to the next task.

Yeah, let's do it.

Lot 5 has been
a better place to look

than just anywhere.
I'm still hoping

to find something interesting,
something valuable, a clue.

Actually, Katya,
you know where I brought

the skid steer in
and disturbed all the soil here?

- Yeah.
- Why don't you scan this?

- What the heck?
- I'd love to do it.

- Yeah.
- That'd be great.

There is definitely
something over here, too.

- Yeah, that's a good signal.
- That's a great signal.

That's pretty deep.

Oh, yeah. That's out.

Pinpoint.

Here we go.

- What do you got?
- Wow.

Here, clean it up a little bit.

That's not just
a shard of metal because

it's got something
going on right there.

There is some
sort of attachment here.

Yeah, looks like
it has a fastener on it.

Tell you what it is,
it's lab worthy. Mm-hmm?

- That's right.
- So, that's good.

- Okay.
- All right, so all this

rigmarole to get that rock
might have been worth it,

- if this means something.
- Mm-hmm.

I mean,
look at the proximity

- to the rectangular feature.
- Right.

Just an inch
or two outside of

where they were digging.

And so,
if this could be a clue

to figure out what
the heck was going on here

and how it associates
to the Money Pit.

Yeah, I think
there's something here.

That's certainly a possibility.

This thing might mean something.

It might tell us
who was there and when

and that would be a big deal.

It could very well
be significant,

so bag it, please,
and we'll analyze it.

Sounds great.

- Let's go onto something else.
- Perfect.

- Way to go, you guys.
- Yeah.

As Marty and the team

finish their
investigation on Lot 5,

in the research center...

So, Sandy, I'd like to
introduce you to Steve Salomon.

...at the request
of Rick Lagina,

Steve Salomon has agreed to
have coin expert Sandy Campbell

examine the 14th-century
Portuguese coin

that was
reportedly extracted from

the original Money Pit
back in 1849.

- So this is it?
- There you go.

Interesting.

With his
extensive experience,

it is the team's hope
that Sandy will be able

to confirm
the origin of the coin,

as well as its potential value.

It's quite cool.

Probably the coolest thing
that I've looked at.

- Really?
- In my time on the island, so...

You know, we've had

some cool things, but...

this is-- this goes
to a different level.

It's a Tornê escudo, which means

a decorative shield.

It's Portuguese, 14th century.

There's clearly a connection

to the Templars because of
the design of this coin.

You have the cross.

- Here it is here.
- And that's basically

the religious Templar

connotation on the back,

and the celebration of
the king on the obverse side.

This would be after
the Knights Templar

were technically disbanded,

but there was still
a lot of involvement

with the monarch
and the Templar.

You know, secretly, obviously.

And this was
an ode to the Templar.

It's a fairly unique

item, because it was only minted

from 1367 to probably '83.

- That's very curious.
- Interesting.

Although the Order
of the Knights Templar

were disbanded in 1307,

their rumored treasures
were never found,

and many fled to nations
that offered them safe harbor,

including Portugal.

Is it possible
that this coin suggests

that their missing valuables
were hidden on Oak Island?

This is exceptional because

this coin,

whenever it was buried,
was brand spanking new.

This was not circulated at all.

You say, "when it was buried."

It was buried for a long time?

Oh, this was definitely buried.

- Why do you say that?
- If this

wasn't buried,
it couldn't look like this.

It would get very dark.

- Mm-hmm.
- If this was sitting

in a chest and protected
down there, it's gonna be

very slow, at 100 feet deep,
for the deterioration.

- Mm-hmm.
- So, this

coin here will have silver,

zinc, copper, and a touch
of nickel when it was made.

We have seen those

elements in
the water testing, though,

- that's been done, right?
- That's true.

- Silver, nickel, zinc.
- Yeah.

Okay, I got to go back

and do my due diligence
here for my dad.

What do you think
it would fetch?

There's a Marty Lagina question,
there you go, right there.

Valuation?

You would be shocked.
This would be

25,000-30,000 dollars.

If you find some

that aren't
deteriorated like this...

...you know, sky's the limit.

That's amazing.

Let's give my Dad a call.

- Hey.
- Hey, Alex. What's up?

So, just a quick question
for you. I need your help

- with some math here.
- Okay.

In the Oak
Island Research Center,

members of the team
call Marty Lagina

to inform him that
the 14th-century

Portuguese coin

reportedly found
in the original Money Pit

back in 1849 may be worth

more than $20,000
in today's value.

So, um, if we have

a coin on the table
that's worth,

say, $20,000, perhaps more...

...what would be
the approximate value of

an entire chest full of those?

Uh, yeah.

According to Sandy,

- it could fetch quite a bit.
- Yeah.

Yep.

Yeah, that's-that's amazing.

Yeah.

Yeah.

There should be more of 'em.

Look, we found all kinds

of really interesting things
and intriguing clues

and... and things
that make you wonder

"What in the heck
happened on this island?"

But it looks quite likely
to me that this coin

is a piece of treasure
that was extracted

from deep in the Money Pit,

and that means
that there's a lot more

down deep
in the solution channel.

Now you can stop

asking me if there's
a treasure in the Money Pit.

I'm on board with that.

- Yeah, we'll keep you posted.
- Thanks Marty.

See you.

The focus here for me is,
you know, why was it put there?

You don't cross
the oceans with money,

put in a hundred-foot shaft,
protect it by

a flooding system.

- No, too much work.
- It just-it just...

it's something else.

Some intent, some purpose.

Truthfully,
if the numbers reached

a billion dollars or even more,

uh... I-I'm not
surprised by that.

But I think there's
something far more valuable.

There's a real treasure here,
a monetary treasure

and something else, secret
information, secret knowledge

that has allowed this
treasure mystery to endure

for 230 years.

I've always believed it,
since I was a little boy.

I believe it yet today
as I sit here.

We just have to find it.

Sandy, Steve,
thank you both very much.

The raising
of the level of excitement

wouldn't have happened
without the both of you.

The Oak Island
story is alive and well.

And at this point,
all that remains

to be said is we need
to go find it.

- Let's go.
- Let's do it.

As Rick and
other members of the team

conclude their meeting in the
Oak Island Research Center...

We'll take that corner

- down, too.
- Yep.

And I'll probably work
with you over here.

Yes, please.

...over on Lot 5,
archeologist Fiona Steele

and other members of the team

continue to search
for clues in the rounded

stone foundation
near the shoreline.

- Fiona?
- Yeah?

I think this is red
with glaze on it.

Okay,
you know what, I think that

looks like the black
Anglo-American ware.

- Yeah.
- The Anglo-American ware

is a coarse earthen ware.

Um, it could be anywhere from

1600s to 1800s.

There's a body of evidence

from the Lot 5 feature
that literally

spans centuries.

How do you explain that?

Good eyes.

The archeologists are
intrigued by the feature, and

more and more
information continues

to come out of the ground.

So, you have to go where
the information takes you.

I found a button.

- Well, hallelujah.
- It's my first button.

Wow, that's good eyes

'cause they are hard to see
when you're with the rocks.

Yeah, you totally
found a button.

- Pretty round.
- Well, and you can see

the shank there.
It's kind of flattened down.

Buttons are falling off
all the time,

and we have found
so many here on Lot 5.

Some of the buttons have even
had military signs on them.

We have found
the starburst button.

That one is really, really old.

That could even possibly
go back to medieval times.

Another mysterious button?

And found close
to where the team unearthed

the so-called starburst button,
which may be related

to the Knights of Malta?

Could the team
have possibly found

another piece of evidence
that may help identify

one of the groups
who used this feature

prior to the discovery
of the Money Pit

and if so,
what their purpose there was?

Every button
that we find adds to our

picture of what we think
might be happening here.

I do think that this
structure is connected

to the Money Pit and
the story of Oak Island itself.

There's so
much evidence in relation

to the artifacts
that give us the timelines,

and these timelines really all
predate the Money Pit discovery.

So, that's why we never
let anything go unexplored.

Yay.

Best find of the day so far.

Well done.

That's exciting.

While the investigation

on Lot 5 continues...

Back in business, Rick.

...several
hundred yards to the east

at Smith's Cove...

- Oh.
- Yep.

- Not that time.
- Another pesky nail.

...Rick, Gary and Billy,

are continuing to search
through the spoils

that were extracted during
the large-scale digs

in the Money Pit area
one year ago.

Hmm, this don't sound bad.
I'll pinpoint, mate.

Let's see if there's
anything in there.

After finding
a tunneling tool one week ago

that may date back to the 1600s,

and possibly connected
to a deposit of treasure,

now they are hoping
to recover a piece

of those potential valuables.

Oh. Nice.

- Chain?
- No, I don't

- believe so.
- No, it's not.

- Some kind of hook.
- Yeah.

My thought is the curve looks
like it's not damaged,

so you could
hang something on there.

That went into the wall,
with a sharpened end,

you hang something
right in there.

- Yeah.
- I mean, it makes sense, right?

Yeah, it looks like,
kind of a...

a refashioned, uh,

square-shanked fastener.

The older type, square-shanked
fastener, to hang stuff.

Yeah, I think this is old, mate.

I think this could go back

to the same period

all the rest of those
iron fasteners and tools

that we're finding
in these Money Pit spoils,

which would be 1600s or older.
That'd be fantastic.

All right, mate, I'll put this

- in the pouch.
- Yep.

I don't think
any of us would want

to quit on this attempt to find
whatever we can in the spoils.

I think
there's more to be found.

It's exciting. The Money Pit

spoils piles are huge

because they accumulate.

There could be anything in them.

The hope is that
we will find some

serious clues associated with

the treasure
in the Money Pit area.

There we go.

Just in there.

Oh, is that it?

Oh!

This is beautiful.

That's really nice.

Oh, beautiful, square nail.

While searching
through last year's

Money Pit spoils, Rick, Gary

and Billy have just made
an exciting discovery.

And that looks suspiciously
like our old friend.

- Rosehead.
- Yep. You got that right, mate.

That's a rosy.

There's a whole lot of rosy

- going on here.
- Yeah.

- It's cool.
- It's definitely

an old fastener.

There's no mistaking,
when you see that

beveled edge going around there.

They made the shaft, and then
did the head separate.

And when this
was hammered into wood,

that's when all these
facets were made.

They resemble
those rosehead petals.

- Is it broken off, or...
- Oh, yeah.

Yeah, that would have
been twice as long.

And if you look at the size
of it, it would have been a lot

bigger. We're on
a treasure hunt, mate.

That could have been
out of a treasure chest.

- Really could.
- Could have.

You've got a big chest,

and you've seen
these silver coins.

I mean,
they would have been heavy.

They would
have needed a big chest.

To your point,
it's not like they're only for

- creating shafts.
- No.

You can look at
old doors and chests,

and you see
rosehead spikes all the time.

Will it connect in some way

to the efforts done long ago

in the Money Pit
and Smith's Cove?

That's the hope.

Okay, mate, that's
a really great find, mate.

Do you want to do the honors and
put it in the bag of goodies?

Sure, that's got to
go to Emma, obviously.

- It's a cool find.
- Yeah.

Stock up
with coffee because

you're gonna be busy, Emma.

As the search
for evidence of treasure

continues at Smith's Cove...

Hey, Steve. How you doing?

- Hey, guys.
- Got to the bottom of J-9?

Yep.

...in
the Money Pit area,

Terry Matheson,
Charles Barkhouse

and Steve Guptill
are about to examine

the final two core samples

that were
recovered in borehole J-9

that reached the bottom
of the solution channel

at a depth of 216 feet.

Hit the bottom of
the solution channel at 216.

That's 26 feet of
recovery. That's pretty good.

Got some loose
material here that looks

kind of intriguing
and interesting.

It's potentially the kind
of stuff we're looking for,

something that might
indicate there was

a treasure chest in
the immediate vicinity,

or some treasure
broke up in the area.

Yeah, I hadn't
run my pinpointer

over it yet, so I'll do that.

Every single one of these cores

needs to be metal detected
because this is

the heart of
the solution channel,

and this is the depth where
we're looking for treasure.

Any time we see
that loose material

in the solution channel,
that means that treasure

can fall to the bottom
when we see that.

It's clean, gentlemen.

It's not gonna be in this.

You know what, though?

We got good information.

This is one of
the deepest hits we've ever had

in the solution channel,
so we know it's a deep canal

- or channel in here, at least.
- Yeah.

I think Emma should look for,
uh, precious metals in this.

I think you're right.
I would say this area between

208 and 211 is the loosest

and, potentially, there
could be something in there.

Something that might indicate
there's some treasure

- in the area.
- Yeah.

Back in 2024,
the team conducted

new water tests here
that confirmed high traces

of gold and silver more than
100 feet underground.

Two weeks later...

Stop.

It's caving.
It's caving all the way back.

...the ground
in this area collapsed

as the team conducted
a major excavation,

which lead them to believe

that the possible
treasure now lies

more than 200 feet deep
in the solution channel.

Now the team
is collecting soil samples

to have them tested
for more trace evidence

of precious metals.

- Feel how loose that is.
- Yeah.

- Here we go. That does it.
- Yep.

If those tests
yield positive results,

it will help the team plan

their most ambitious
excavation yet in the hopes

of finally recovering
the long-lost treasure.

The next hole, we're not
gonna go far from this hole.

All right,
I'm gonna go drop the gyro.

- Okay.
- We'll get that information

- and we'll move on.
- Yeah.

- Absolutely.
- Absolutely.

As a new day dawns...

...and while members of the team

begin drilling a new borehole
in the Money Pit area...

On Lot 5,

there's a mystery there
wrapped in an enigma.

...Rick Lagina

and members of the team
have joined

Laird Niven and Emma Culligan

in the Oak Island Laboratory.

I mean, it really is confusing.

But in its confusion,

artifacts come up
to the surface, right?

We have one here.
Katya and Peter

and Marty found it.

Laird and Emma
have just completed

their preliminary scientific
analysis on the metal artifact

that was unearthed
one day ago on Lot 5.

What I think is really cool
about where we found this

is it was really near
the rectangular feature.

Then Katya came through

and was metal detecting
on the tracks.

And this is where we found that.

So it was kind of
the skid steer turning up

a little bit of the material
that brought this to life.

Emma, what can you
tell us about that?

So it is a cast-iron pot.

There is
a slight phosphorous content.

But this would not affect

the quality of the iron
whatsoever

- because it is cookware.
- And you're certain

that that's what that is
based on the curvature?

That's what we think.

- Yeah.
- The high phosphorous

content that's present
throughout an iron

creates an iron that is brittle
during colder climates

and it's prone to breaking,

which suggests

it being pre-1800s.

I find that
Industrial Revolution

is when they really started
to stray away

from cast-iron pots.

So it fits in
with the time period of 1700s.

It could

- go into the 1600s.
- Wow.

Quite stunning.

Oh, my gosh.

So, this cast-iron pot

fits in with the time period
of 1700s.

It could go into the 1600s.

Oh, my gosh.

In the Oak Island Laboratory,

Emma Culligan
has just informed Rick Lagina

and other members of the team

that the remains
of a cooking pot found by Marty,

Katya, and Peter
one day ago on Lot 5

could date as far back
as the 17th century.

So, this was probably
used by someone who was

associated with the features.

- Mm-hmm.
- Yeah. That's-- I think that's

a reasonable assumption.
And the neat thing

about cast-iron pots is
I don't believe in the 1700s

they had the ability to cast
anything in Nova Scotia.

- No, they didn't.
- So it was made in Europe

- and then brought here whole.
- Yeah.

Could Laird be correct

that this piece of a possible
17th century cooking pot

was likely brought to Oak Island
by someone of European origin?

If so, who was it?

And what were they doing
on Lot 5?

We've all broken things, right?

If you don't pick it up,
the whole thing's there.

- Yeah.
- Is this island just strange

- with all of these one-offs?
- So between

the round feature
and the rectangular feature,

we have hundreds

of pieces. But nothing whole.

We certainly haven't found
a whole pot.

No. And that's what's troubling
to me, is...

is this an attempt by whomever
to police the site?

- To hide something?
- I-I don't know

if they just picked up
the larger pieces

and threw them in the ocean

or took them with them.

The foundation itself

before it was discovered
was under

several feet of soil,
was it not? Yeah.

- Yeah. And rocks.
- So everything's well-covered.

It's a possibility
they were hiding

- something there.
- Yeah.

Everything that comes from Lot 5

hopefully can help
solve that mystery.

'Cause if you can put this back
in the 1600s,

then the "who" becomes
maybe attainable, right?

- Yeah. I agree.
- Right around

that area, we had found
trade weights,

buttons that connect
with the Knights of Malta,

some other very old,
um, artifacts.

But we get
something different here.

- Yeah.
- That could be important.

That cast iron may give us
a clue to who else

was active in that area.

Could Rick and Doug be correct

that this fragment of a cooking
pot offers more evidence

that someone deliberately
covered up the two foundations

as well as all traces
of their activity on Lot 5

back in the 1600s?

If so, could other potentially
17th century artifacts

that have been uncovered nearby
help identify just who it was?

Truthfully, I wish I could say,

"Lot 5 was done
by this group of people."

Could it be the Knights of Malta

or something associated
with the Templars?

Sure, it could.

But some of the artifacts
go back into medieval times.

You know? 1400, 1500, 1600.

But for right now,
I think we're done.

- We need to get back to work.
- All right.

- Thank you both.
- See y'all.

As Rick, Peter, and Doug

conclude their meeting
in the lab...

Okay, Katya. We're on.

We're on Lot 5.

And this thing
has given up a lot.

But today
it's gonna give up more,

- right?
- I'm hoping.

...on Lot 5,

Marty and Katya
are expanding their search

south of the rounded feature

to look for new clues.

Yes, sir.

Aha.

That sounds pretty good.

It does. It's
registering pretty good.

And it looks nonferrous,

- so...
- Let's have a go.

Right under that rock.

- Come on. Be something good.
- Come on.

All right. Maybe that
might've loosened things up.

Ooh. That sounds
a lot better out.

Let's see.

- There you go.
- There we are.

Ooh! A button?

What is that, a coin?

I don't think that's a button.

Wowzer.

- Does it look like a coin?
- I think that's a coin.

I think
that's a really old coin.

All right! Way to go, Katya!

That looks like
a very old coin to me.

Oh, my gosh. It does.

It almost looks like
there's a cross on it.

Really?

Oh, yeah.

- Right there and right there.
- Mm.

I think it might be copper,
'cause it's...

- Yeah, I think it's copper.
- It's tinted green,

and only copper does that.

A coin is really exciting.

Katya and I look at each other,
and, you know, I know what's--

I know what she's thinking,
and I know what I'm thinking.

This is the Roman coin area.

And that is, you know,
hugely exciting.

Hey, you nailed it.
You said it was nonferrous

- right off the bat. Good on you.
- Thank you.

- I'm impressed.
- I'm so excited about this.

- This is amazing.
- I feel pretty good about this.

Okay, Katya, let's--
let me call big brother.

Honestly, he'll
want to see this.

Okay. All the smiles.

Proud dad coming in.

- Yeah, Dad coming in.
- On Lot 5,

Rick, Gary and Billy arrive

after hearing
that Marty and Katya

have found
a potentially important clue.

Come on over here.

We think this is good.

When Marty calls,

- got to be good.
- Gary, come here.

I'm coming!

I'm telling you this-- your
daughter was pretty excited.

Ready?

Oh...

That is...
Oh, that's nice.

Mm-hmm.

Ooh, that's old.

- Is it?
- Yeah.

It might be identifiable,
'cause there is writing

around the edges.
Partly corroded away.

Yeah. Definitely not
a button. That's a coin.

- Mm-hmm.
- This-- this is pre-1600s.

Yeah, this is an old one.
Wow.

- Did me proud, Katya.
- Thank you.

Could Gary be correct

that this copper coin
may be more than 400 years old?

If so, might it be related
to the Portuguese silver coin

and help identify just who was
behind the Oak Island mystery?

The more you look at it,
the more stuff

you can see on it.
So the lab's gonna see stuff.

- Yeah, this...
- Yeah.

- The CT scanner will.
- Mm-hmm.

Yeah.

- It's irregular shaped.
- Mm-hmm.

It's nice and thick.

- Yeah, that's...
- But it's also not...

it's not, uh, deteriorated.
I'd like-- You know, I think

it just was that...
sort of like a crude shape.

Older metals
also have purer compositions.

You know, the metals are just...
They're better.

They don't rot like, you know,

the nails I've been finding.

This would be a hammer coin?

Yeah, it would have been
an hammered coin.

Oh, my God.

That is absolutely gorgeous.

I just hope it tells a tale.

I hold the coin, and...

I can see things on the face.

So, at that point, it's
really become quite exciting.

I mean, we've already found
five coins,

Roman era coins,

on Lot 5 that have been
authenticated metallurgically.

The coin will tell you
what it is.

And that, uh...

provides immense hope
amongst all of us.

That's a top-pocket find.

- You ain't got any top pockets.
- I know.

- That's what Dad's for.
- Well done, Katya.

- Thank you.
- That is brilliant.

Makes me proud.
That's fantastic.

- That means the world to me.
- Yeah.

- Let's get back to work, Katya.
- Great find.

That's cool.

The new discovery on Lot 5

and the revelation of a 14th
century silver Portuguese coin

suggest that the legends
of a sacred

and incredibly valuable treasure

may really lie buried
on Oak Island.

But as Rick, Marty,
Craig, and the team

dig deeper than ever
in the Money Pit,

will they find a cache of coins

that could literally
be worth billions?

And might that
be only a small portion

of what lies hidden below?

Next time on The Curse
of Oak Island...

It's a brand-new area
we haven't explored

on the western side.

- Oh. Whoa! What we got here?
- Look what I'm getting here.

- Oh!
- So I've done a CT scan.

You can see it
faintly right here.

- Well, I'll be damned.
- Yeah.

That might tell a story.

- Whoa! Whoa!
- We're probably in the void.

If there's "the one thing."

He could have it
in that core barrel right now.

- Yeah.
- There you go.
