I have a lot of pennies, its not a secret. I collect them any chance I get, but only the ones from 1982 and earlier. All pennies after that year switched to a mostly zinc alloy, meaning theres significantly less copper in modern pennies. Well, my original idea was to stockpile them so i could melt them down into ingots and tokens (just for fun) but I became too attached to them. I've found a lot of cool coins in the process.
