Im pretty sure its not a proof but just wanted other opinions. I realize its beyond rare to find a proof coin in circulation. Just curious.
Sometimes proof coins can be found in circulation usually impaired but that isn't one (of the very rare 1968 no S proofs) it's just a regular business strike.
When I was searching rolls, I had better luck finding impaired proofs of Kennedy half dollars. I still have about one dozen of them. Chris
