U.S. Mint Marks
Mint marks (often spelled mintmarks) are small letters designating where coins were made. U.S. coins struck (i.e., minted) at Philadelphia before 1979 (except 1942-45 nickels) do not have a mint mark. Starting in 1979, a letter P was used on the obverse (front) of the dollar coin (Anthony dollar), and thereafter on all other denominations except the cent (penny). Mint mark position is on the reverse of nearly all coins prior to 1965 (except the cent), and on the obverse after 1967.
