The coin in question is a 1975 Roosevelt Dime, issued by the United States Mint in Philadelphia. This particular specimen is notable for being a Proof version, which means it was struck with special care to produce a high-quality finish with a mirror-like surface and sharp details. The coin features the iconic design by John R. Sinnock, depicting the profile of President Franklin D. Roosevelt on the obverse and a torch, olive branch, and oak branch on the reverse, symbolizing liberty, peace, and strength, respectively. The Roosevelt Dime has a denomination of 10 cents (10¢) and is composed of a blend of 75% copper and 25% nickel, encasing a pure copper center. With a diameter of 17.9 mm and a weight of 2.27 grams, this coin has a reeded edge, which helps prevent counterfeiting and adds tactile detail. The 1975 production saw a total mintage of 2,845,450 coins, making it relatively common, but the Proof version is sought after by collectors for its superior quality. This Roosevelt Dime is part of a long-running series that celebrates the legacy of a significant American president, and it remains a popular choice for both numismatists and those who appreciate American currency. This example, minted without a mint mark, encapsulates a moment in history and represents a piece of American economic heritage.
