GUEST: I found it on an auction site.

It's marked Tiffany and Co., and that it was made by Longines for Tiffany and Co.

And I thought, "Let me grab that real quick," 'cause it was priced super-low.

And I get the thing in the mail, and I, I see that it has someone's name written on it, Mary Corbit Warner's name.

And she lived in Odessa.

APPRAISER: Where's Odessa?

GUEST: Uh, it's in Delaware.

It's, uh, called, uh, the Sharp-Warner House, I believe, in Odessa?

APPRAISER: Okay.

GUEST: That she had given to the state of Odessa.

When I was, uh, reading more and more about it, her family just became so interesting.

I guess they'd hid a slave there from the Underground Railroad.

APPRAISER: I followed up on your story, and the Corbit House is a famous house.

It's a museum now in Odessa, and it's actually a National Historic Site.

GUEST: Mm.

APPRAISER: The story about the Underground Railroad is also correct.

So this is by Tiffany and Company.

They've been around since 1835, very prominent designer company in New York.

It's sterling silver with niello.

And what they did was, they would engrave the silver out and put this material, niello, in there, and they'd bake it on there... APPRAISER: ...to give it this beautiful look.

So I opened it up and I saw the signature in there, the Mary Corbit Warner, and it's dated 1911.

However, I do believe that the watch is from the late 1800s.

So it also comes with this chain.

It is original to the era.

I don't n, necessarily know that it's Tiffany.

There's no marks on that indicating that.

GUEST: Mm-hmm.

APPRAISER: It's gold-filled.

GUEST: Okay.

APPRAISER: Meaning it's covered in gold-- basically, gold-plated.

Still in great condition, and it has this nice little opal set in the slider there.

Can you tell me what you paid for it?

GUEST: $360.

APPRAISER: How much do you think it's worth?

GUEST: Oh, goodness.

(chuckles) I would imagine maybe $600?

APPRAISER: I believe that, in a retail environment, it would sell for around $2,000.

GUEST: Yay!

(laughs) I would hug you-- I, like, I don't know if... But yeah, I would, I would hug you.

APPRAISER: In a minute.

GUEST: In a minute, I'm gonna jump over the table and hug you.

(chuckling) That's awesome.
