HarveyJMartha Posted September 2, 2013 Report Share Posted September 2, 2013 Please share its photographs with us. The 1990 No S Lincoln coming from an extremely popular Lincoln series is the only proof coin from 1909 till today that lacks a significant mint mark.

Steve D'Ippolito Posted September 3, 2013 Report Share Posted September 3, 2013 Please share its photographs with us. The 1990 No S Lincoln coming from an extremely popular Lincoln series is the only proof coin from 1909 till today that lacks a significant mint mark. My impression was that proofs were made by the Philadelphia mint (hence no mint mark) through 1964. Am I having a moment of cranial flatulence here?

HarveyJMartha Posted September 26, 2013 Report Share Posted September 26, 2013 “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. Amazingly, the 1990 No S Proof Lincoln cents deceived both the Philadelphia and San Francisco Mint employees.” Source: http://www.pcgs.com/top100/coin9.aspx Quote Link to comment Share on other sites More sharing options...
