Hello everyone. I’m brand new to this forum; actually, this is my first post. Like many before me, I apologize if I have posted this question in the wrong area and/or if this has been asked by others before me. With that said, I discovered this 1981-P Kennedy Half Dollar the other day, and I just curious as to why it has this “odd finish.” No, I don’t believe it’s anything of value, but would love to know what others think so to expand my knowledge in numismatics. Thank you.
Welcome to CT! This appears to have been treated with something; likely a bath in acid or something similar.
Welcome to CT! From the pictures, it looks like someone attempted to clean the coin. This effect happens with pennies if you soak them in white vinegar for a period of time. Don't do this though, as it can completely ruin the luster and value of a coin. For future reference, this would most likely fit better in the error coins forum. Since you are new, posting here is ok, but for future posts I'd recommend that.
Hey, welcome to CT. This kind of finish is found mostly on coins that have reacted with some sort of acid, either from environmental exposure or deliberate.
Welcome to CT. Looks like ED, environmental damage. Either someone "treated" the surface, or it may have laid in acidic soil for a while.
