This has been in my collection for 40 years. Not sure how I come to find it. Anyway, it has a funny goldish finish and an extra piece of copper coming off the top of the coin in the back. What do you think? Penny on the left. (Right is for comparison in color. thanks) .

Looks like it may have been plated and once been attached to something, keychain or something along those lines. Definitely not something that could have happened during minting.

Thanks for your 2 cents... why would someone attach the coin to something?

Probably there's thousands of examples of pennies being attached to things.

The real question when you find something like this is "Could this happen during the minting process?" The minting process is a well understood relatively simple manufacturing procedure with every step fully documented. Every error coin has one thing in common, there is point in the process where it can happen and it is known how they happen. Once they leave the mint however, there is an unlimited number of ways they can be damaged or altered and it is not always possible to know how. If it is impossible for it to happen during minting though, that leaves post mint alteration or damage. There, my explanation should be worth at least three cents now.
