This description pertains to a highly collectible coin from the United States: the 1939 Washington Quarter. Struck in Philadelphia with a mint mark of 'P', this coin qualifies as a Proof, meaning it was specially produced for collectors and exhibits a high level of detail and finish. The coin has a denomination of 25 cents, commonly referred to as a quarter. Crafted from silver, it weighs 6.25 grams and has a diameter of 24.3 millimeters. Notably, this particular 1939 Washington Quarter has a very low mintage, with only 8,795 pieces produced, which greatly enhances its desirability and value among numismatists. Given its characteristics—being a Proof coin made of silver with such a limited mintage—this piece is not only a representation of the classic Washington Quarter series but also a rare find within the broader realm of American coinage. Collectors and investors often seek coins like these for their beauty, historical significance, and potential for value appreciation over time.
