I know these posts are probably annoying but I really don't know how to tell the difference. Is this an error? I'm talking about the rim on the reverse side.
Your posts are never annoying. It's a good thing that you ask us. That's the best way to learn. And it takes a lot of time to understand the difference between an error and PMD. Unfortunately the rim took a hit and it's not a mint error of any kind. Just damage. Keep asking away!
Just an error on that one but please, never be afraid to ask us. That is why a number of us are here.
Hi Shirley - here’s something to keep in mind: older coins worked harder than newer coins. This is in part because coins had buying power. Vending machines of all sorts were more plentiful than they are today and novelty/candy machines operated on lower denominations. Many had turnstile crank handles and prime for burnishing material. That may have happened here but who knows. For example, CRH enthusiasts will often find pre-70s nickels with radial grooves and scratches at the center of the nickel. As others have noted here, ask questions to learn. Many here are happy to offer up knowledge and information.
