APPRAISER: So, tell me where this came from.

GUEST: Um, I inherited it from my paternal grandparents who inherited it from their employer when he died, and they, um, received all of his personal property.

APPRAISER: So it's been in your family for how many years?

GUEST: About 64 years.

APPRAISER: 64 years. I am going to tip this over. And we have... "Louis Comfort Tiffany," and we have prefix R and a number. The prefix R designates that this is 1899 from the Tiffany Glass and Decorating Company. And it's a leaf and vine pattern. And it's called Paperweight because it's encased with different colors of glass, which gives you all this paperweight effect. Unfortunately, if we tip it this way, we can see that it is badly cracked.

GUEST: Mm-hmm.

APPRAISER: It's called a maker's crack. And that's common on these pieces. And, of course, it does hurt the value of the piece. Also inside, we have quite sick glass, which is that white, milky color.

GUEST: Mm-hmm.

APPRAISER: It's pretty devastating on this piece.

GUEST: Oh...

APPRAISER: Not great news. But, this piece, as it is-- as is-- which, on most pieces, it would ruin the value completely with this kind of issue...

GUEST: Mm-hmm.

APPRAISER: This piece is still worth $3,000 to $5,000.

GUEST: Great.

APPRAISER: Now, I do have another question. Have you ever weighed this thing?

GUEST: Um, no, I haven't, but it's about the weight of my bowling ball, which is about...

APPRAISER: Your bowling ball! (both laughing)

GUEST: Which is about...

APPRAISER: I like that.

GUEST: Nine or ten pounds.

APPRAISER: I like that!

GUEST: It's very heavy.

APPRAISER: In perfect condition, this would be worth $80,000.

GUEST: Wow. Wow.
