Collectible coins in the United States include a variety of denominations, designs, and historical significance. The 25-cent coin, commonly known as the quarter, features the likeness of George Washington, particularly the Washington Quarter series introduced in 1932. The 1966 Washington Quarter was minted in Philadelphia and is part of a larger series that includes various design changes, commemorative issues, and significant minting events. Collectors often seek out quarters based on their year, mint mark, and condition, with certain issues commanding higher values due to rarity or unique characteristics.
