APPRAISER: You brought in a box of your mother's jewelry that she collected over the years.

And how many pieces do you think was in that box?

GUEST: I'd say 100, maybe.

APPRAISER: About 100 pieces.

GUEST: And at the very bottom of it, I found this little guy.

APPRAISER: This is called a trembler, or the French term is "en tremblant."

In the 1700s, they did "en tremblant" pins that were flowers that were worth thousands of dollars.

This is from the late '30s and 1940s.

It's pot metal, rhinestones, has two precious little Scottie dogs, a very stylish lady with rhinestone embellishments.

What do you think she might be worth?

GUEST: A good bottle of wine?

(laughing) APPRAISER: That's a, that's a great idea.

No, she's worth about $300 to $400.

GUEST: Oh, my .

APPRAISER: Yes.

GUEST: Well, that is surprising.
