The coin in question is a 1977 San Francisco Mint Roosevelt Dime, which is a ten-cent piece struck for circulation in the United States. This specific coin is part of the Roosevelt Dime series, featuring the effigy of President Franklin D. Roosevelt, who was in office during the Great Depression and World War II. It was minted in a proof production type, which means it was produced with a higher level of care than standard coins, resulting in a polished finish and sharper details, aimed primarily at collectors. The coin has a diameter of 17.9 millimeters and weighs 2.27 grams, constructed from a composition of copper-nickel clad copper, which gives it a distinct appearance compared to earlier dimes made entirely of silver. Its mintage figure stands at 3,251,152, indicating the total number of coins produced at the San Francisco Mint for that year. Given its qualities as a proof coin, along with its lower mintage in the context of the Roosevelt Dime series, the 1977-S Proof Roosevelt Dime can hold additional value for numismatists and collectors seeking to complete their collections or invest in U.S. coinage. Overall, this coin exemplifies both historical significance and collectible appeal within the realm of American currency.
