I Stumbled onto your forum awhile back after buying a 1964 Clock. Since then I've increased my coinage, but aimsley bounced around the net for knowledge. Funny story about the clock. I found it at a garage sale. I knew right away they were silver 1964 coins in the plexiglass. It had no price on the clock, so I inquired to the middle aged woman running the sale. She said "It don't work!". I said okay? so how much? She said $3. I paid and left. Later while I was telling the story to someone, he said you stole it. I replied with a shoulder shrug and said "Well, It doesn't work".
I actually didn't know how good of a deal I got when I paid for it. I might have given them more.
ETA I've been doing some coin rolls and have a fair amount on Wheat Pennies, Nickels and some Silver. Also some misc. older coins. Found a hand full of error coins that intrigue me. I'll be posting more on those as I learn.
