Howdy,
I'm new to collecting and
very new to any mint error coins, so I don't know what I have here. It's a 1955 Dime ('S' Mint?) where it seems to maybe have been stamped too hard or something. Or there was too much silver and it overflowed the die, I don't know. But front and back sides are recessed within a smooth outer ring. I've attached pics, so I hope this suffices. Please let me know what you think!
