The silver dime was last minted in 1964. Also called the Roosevelt dime, there were 1,357,517,000 dimes printed in 1964 bearing the face of President Franklin D. Roosevelt. The Roosevelt dime replaced the dime bearing the likeness of the Roman god of war Mercury in 1946 to honor the president who passed away the year before.
Although the first dime was first minted in 1892 with the disme (as the dime was spelled in the Coinage Act of 1972), the coins were only struck in copper and were never circulated. The first silver dimes were minted and circulated in 1796 with the Draped Bust design. This design, which had 31 different versions, contained 89.24 percent silver and 10.76 copper. The Draped Bust was replaced with the Capped Liberty design in 1809.
The Capped Liberty dime continued to be minted until the Seated Liberty design replaced it in 1837. The silver content in the Seated Liberty dime was 90 percent with 10 percent copper. This metal composition in remained until the last silver dime was minted in 1964.
In 1892, the Capped Liberty dime was replaced with the Barber design, which was minted until 1916. The Winged Liberty Head design, better known as the Mercury dime, replaced the Barber dime and was minted until the Roosevelt dime replaced it in 1946.
Although the Roosevelt dime design remains, the Coinage Act of 1965 drastically changed the metal composition of the dime. Since 1965, dimes were made out of 91.67 percent copper and 8.33 percent nickel.
