1974 was the last year the San Francisco Mint issued Lincoln cents for general circulation.
Since 1968 San Francisco has struck proof coins, including cents, that all carry the "S" mint mark. However they no longer make coins for circulation. San Francisco struck pennies nearly every year from 1908 to 1955. The mint was deactivated from 1956 to 1964. In 1965 it started producing circulation coins and Special Mint Sets during the great coin shortage but none of these carried a mint mark. The S mint mark was returned to circulating cents minted from 1968 to 1974, but those were the last ones minted up to the present.
