I have 3 pennies here all of which have been found coin roll hunting. Please let me know your thoughts and value if any. First I have a 1976-D liberty bell and USA outline of the United states. The reverse appears to have glue on it as it was more than likely in an album of some sorts. Second I have a 1971-S coin which has no reverse. It is extremely smooth and slick is it a blank planchet or was it filed down after words. It appears to be the same thickness as a noral penny. Let me know your thoughts. Last I have a 1935 wheat penny that appears to have an error or issue on the obverse of the coin. Is it valuable or after mint? Again thank you for all of your thoughts and feedback. Very much appreciated.
The 1976-D is whats called Counter Stamped and was done by someone or entity after left the mint. The 1971-S is Post Mint Damage, meaning someone ground the reverse off with some sort of grinder or something. You can tell because of the lack of the rim. The last coin is hard to see you might want to take it out of the flip so we can get a better look?
The 1935 could be a die crack or a lamination error. I agree with @coinguy-matthew with the others and we do need a better close-up of the '35 outside of the 2x2. Chris
Thanks for the responoses. See attached pics for the 1935. What are values on the 1976? And value on 1935?
