Probably a lot of fingerprints, as it came out of a vending machine. I'm new to this, so I don't know what you're getting at, other than uncirculated vs circulated. Circulated double die coins aren't worth anything?
Welcome to the forum friend. I think you have a case of die deterioration. Not a doubled die. Dont give up.
I also say no FYI - the correct Numismatic Terminology is Doubled Die.. not double die. Big difference! Welcome to CoinTalk Peace
