The coin in question is a 1965 Philadelphia Mint Roosevelt Dime, a component of the United States currency system. This particular dime, denoting a denomination of 10 cents, is made from a copper-nickel clad copper material, which consists of a core of pure copper sandwiched between layers of nickel. It has a diameter of 17.9 mm and a weight of 2.27 grams, typical for dimes minted during this era. Bearing the mint mark "P," which indicates its origin from the Philadelphia Mint, this coin is part of the Roosevelt Dime series, established in 1946 to honor President Franklin D. Roosevelt following his death. The coin's mintage for the year 1965 was remarkably high, with a production of over 1.65 billion pieces, making it one of the most commonly found dimes in circulation today. With no specific height or width due to the standard round shape of dimes, and a currency amount of 0.10 USD, this coin serves both as a unit of currency and as a collectible item, valued for its historical significance rather than for any particular rarity. Its modern relevance lies in its circulation history and the embodiment of American monetary policy during the 1960s.
