I'm unable to find information on this error. The "O" in "One Cent." Is this worth anything? I know most errors are DD.
Welcome to CoinTalk Levin. Your coin is not a mint error. It took a hit in circulation. The metal is soft a easily moved by damage. Not a doubled die.
A "penny" with no mint mark indicates it was minted at the Philadelphia Mint. Welcome to CoinTalk @Levin Mancill !
I know it's not a double die. But this doesn't appear to be a post circulation error with the cud mark right next to it as well.
