Collectible coins, such as the United States 25 cents quarter, often attract numismatists for their historical significance and rarity. The Washington Quarter, first minted in 1932, features a portrait of George Washington and is widely collected. The 1964 Washington Quarter, particularly from the Denver mint, is notable as it marks the transition from 90% silver to clad coins in subsequent years. Collectors frequently seek out these coins in various grades, with uncirculated or higher-quality examples commanding premium prices.
