Roosevelt Dime history

The Roosevelt dime debuted in 1946, shortly after the death of President Franklin D. Roosevelt. The choice was closely connected to Roosevelt’s support for the March of Dimes and the campaign against polio. John R. Sinnock designed the portrait and reverse torch motif. The coins were 90% silver through 1964 and changed to copper-nickel clad in 1965; the familiar Roosevelt design continued through 2025 before a one-year Semiquincentennial design replaced it in 2026.
