GUEST: I grew up with this clock, um, in my grandmother's house.

It was the one-- one of the items from my grandmother's house that I remember more than anything.

And, uh, the big story that I remember the most with this clock is my mom always used to tell a story about how, uh, it magnifies sunlight.

And so, it was on there-- on a little end table by one of their couches.

And all of a sudden, the couch started smoking.

APPRAISER: (laughs) GUEST: So, it caught-- yeah, the couch at my mom's house on fire.

So now we always need to make sure that we don't have it anywhere near the sunlight.

APPRAISER: Yeah.

GUEST: So, it's got to be in the center of the room, not by a window, uh, so we don't start any more fires with it.

APPRAISER: It's unbelievable.

GUEST: Yeah.

APPRAISER: Do you know what it's called at all?

GUEST: I don't know anything about it, I just always loved it.

I've never seen anything like it.

I don't, I don't know what it's called, no.

APPRAISER: It's called a crystal ball clock.

GUEST: Okay.

APPRAISER: And there's two reasons why it's exceptional.

First of all, the size.

It's just a little smaller than a volleyball.

This is scaled up ten times the norm, and, and I've only seen one other that's this big.

And the second thing is the complications that it has.

It has, uh, the calendar, uh, numerical date, the day of the week, and then the moon phase at the bottom here.

And all the hands you said are off of it, but they're inside of it, because it got shaken.

GUEST: Right, they're inside it.

Yeah, it got-- it got shaken, so.

APPRAISER: And that's a great thing, that you have the hands inside of it.

Probably made circa 1890, and it's of French origin.

It was really nice quality thing.

I would put a value on this clock that burns couches, uh... (both laugh) Probably about $3,000 in its present condition.

If you put the hands back on it and you get it serviced, I could see it being worth as much as say $4,500.

GUEST: That's great.

It's going to stay in my living room for the foreseeable future.

I love it.

APPRAISER: Right.

And maybe put a fire extinguisher next to it.

GUEST: (laughs)
