GUEST: I like to go to old jewelry stores in little towns and ask the jeweler or the watchmaker if they have any old pocket watches they want to sell and... I found this as well. The jeweler was telling me he didn't want to sell me any of his pocket watches, and I looked up on the wall behind him and saw this clock and made the other mistake that a collector can make, which is, I said, "Wow!"

APPRAISER: Prior to 1850 or so, almost every city in the country kept local time, which was independent of all the other times.

GUEST: Right.

APPRAISER: But this clock represents a transition between the 1880 period, when we knew there was a need for time zones and so on and actual time zones. It shows... here the railroad time, but down here, in Indianapolis, we're an hour ahead, so it shows the local time.

GUEST: Solar time, right.

APPRAISER: That's right. I think we have to say that its replacement value would be about $7,500.

GUEST: Great, that's wonderful.
