onejinx Pillar of the Community United States 1231 Posts	Posted 09/10/2008 7:52 pm This is on a wall of a downtown Minneapolis coin dealer. 100,000 cents It is quite the site to see. And the dealer was very pleasant to talk and deal with when I went. Edited by onejinx 09/10/2008 7:52 pm Report this Post to the Staff

biokemist6 Bedrock of the Community United States 12437 Posts	Posted 09/11/2008 12:02 pm I would bet that each coin in a stack is glued together but the stacks might not be glued together. I would think it would just be too unstable without them being glued into stacks- one little bump and you have a big ol' pile of copper on the floor I am not saying you would need some industrial strength epoxy or anything, just a small drop of Elmer's glue would be enough for stability and they could still be easily taken apart. Pretty dern cool nevertheless Report this Post to the Staff
