Collectible coins refer to coins that are sought after by numismatists for their historical significance, rarity, or condition rather than their face value. In the United States, the 25-cent quarter is among the most iconic coin types, particularly the Washington Quarter which features a bust of George Washington. The 1986 Denver minting of the Washington Quarter is part of the series that began in 1932 and is notable for its value to collectors depending on factors such as mint mark, condition, and any unique variations.
