Notes:
Franklin Delano Roosevelt was one of America's most popular and influential Presidents. His portrait was placed on the Dime in 1946, following his death in 1945. The designs were by John R. Sinnock, whose initials "JS" appear below the tip of Roosevelt's bust on the obverse of the coins. 1964 was the last year that Dimes were struck in silver -- from 1965 on, Dime blanks were made of copper-nickel over a copper core.
From 1968 onward, mint marks appear above the date. Those struck in Philadelphia carried no mint mark until a letter P was introduced beginning in 1980. Roosevelt dimes coined at the mints in Denver and San Francisco have always been identified by letters D and S, respectively, except during the years 1965-67 when these mint marks were omitted.
