A 1977 dime is generally more valuable than its face value of 10 cents. Its actual value will depend on the condition of the coin and its type.
On a sliding scale depending on the coin's condition, a 1977 dime may be worth several times its face value. The dime may show a mint mark of either S or D above the date.
The Roosevelt dime features a portrait of the former president. Its design has been in use since January 1946 in commemoration of not only his presidency but his efforts in founding the nonprofit service organization that would become the March of Dimes Foundation. Roosevelt dimes produced after 1965 comprise a layer of copper sandwiched between layers of a nickel and copper alloy.
