Richard:
I am not a Coke Product collector. I am however an ardent clock collector, I have German cuckoo clocks, wall clocks, mantle clocks, a myriad of novelty clocks (German and Japanese), and a Grandfather clock. When a new hour arrives at my house, you know it! I think my all time favorites are the cuckoos. I happen to know that what you have here is a good find. It certainly looks to be in mint condition. This piece has a lot of detailed carvings, the finish looks great, the silkscreened glass looks perfect, and you say it's from 1900, so it's really old. The movement which I'm guessing is either an 8 or 14 day chime movement will need to be cleaned and oiled if it has not been run for a while. If your photos are any indication of the loving care this must have recieved, it's probably in superb condition and good running order. There's probably not a collector around that wouldn't love to have this. I've checked EBAY and antique stores and seen similar clocks in lesser condition go for about $300-$350, but very few in as good of condition as yours, they usually go for about $500 or so.
