This penny has an "O" Stamped on the reverse . Anyone know what this is or how much it could be worth? I havent sent in for grading yet.
I am not seeing it can you take a close up of the area in question? Maybe orient the coin?, I get dizzy trying to look sideways.
Unless you are trying to say it is from a dropped element. http://www.error-ref.com/?s=dropped+element
