The Roosevelt dime was first released into circulation on January 30, 1946, and it quickly gained popularity among the American public. The dime was minted in 90% silver until 1965, after which it was made of a copper-nickel alloy due to rising silver prices. The dime has a diameter of 17.9 mm and a weight of 2.5 grams. Over the years, there have been several modifications to the Roosevelt dime. In 1965, the coin’s composition changed to a clad design, with a copper-nickel core and outer layers of copper-nickel bonded to it. In 1992, the Philadelphia Mint began minting proof versions of the Roosevelt dime in both clad and silver compositions, specifically for collectors. Additionally, there have been various special editions and commemorative versions of the dime released by the United States Mint.
