Helllo everyone! I found this 1957 Lincoln Penny in pocket-change a while back. My first impression was that someone's finger prints was left on the planchette somehow during the minting process. I am new to coin-roll hunting. Any ideas or opinions would be greatly appreciated. Thank you!
They will eventually etch themselves into the coin. Unfortunately your coin is just damaged. A dip in acetone may help but I don't know at this point.
