The coin in question is a 1875 Nickel Three Cents piece, minted in Philadelphia, designated with the mint mark 'P'. This small yet significant denomination has a unique historical place in American numismatics. Made of a copper-nickel alloy, the coin features a diameter of 17.9 mm and a weight of approximately 1.94 grams. The 3-cent nickel was introduced during a time when nickel became a popular metal for coinage, and it was produced as a response to the growing need for small change in the expanding economy of the United States. The 1875 mintage was relatively low, with only 228,000 pieces struck, making it a collectible item for numismatists today. While the nominal value of the coin is just three cents, its collector value can vary significantly based on its condition. The Nickel Three Cents series is known for its distinct design and historical significance, and the 1875 issue is especially valued by collectors of U.S. coins. Whether you are an avid collector or a casual enthusiast, this coin represents a piece of American history worth appreciating.
