I'm just wondering if there's other ways to differentiate between Philadelphia and San Francisco no mint mark? Edited by Ds7ek 02/28/2023 3:23 pm Report this Post to the Staff

Dearborn Moderator United States 96735 Posts	Posted 02/28/2023 3:37 pm On a proof coin the rim would be very square and flat and the fields would be smooth and mirror like (even on an impaired proof), this one is a Philadelphia struck business coin.

lcutler Pillar of the Community United States 1657 Posts	Posted 02/28/2023 5:14 pm About the only way any more are going to be found is in proof sets that haven't been checked. Really no point in looking for one in circulation. Report this Post to the Staff

datadragon Pillar of the Community United States 1648 Posts	Posted 02/28/2023 6:33 pm In 1985 the U.S. Mint abandoned the practice of punching mint marks into working coin dies and instead, it began punching the mint mark directly onto the working hubs. However, the 1990 No S Proof Lincoln Cent was inadvertently struck by a mint state die that had been processed as a proof die. This occurred because the Mint had shipped a mint state die to the San Francisco Mint without the die containing the S mint mark.
