Collectible coins refer to numismatic items that are valued for their rarity, historical significance, or aesthetic appeal. In the context of the United States, the 25-cent quarter, commonly known as the Washington Quarter, was first minted in 1932 to honor George Washington. The 1989 Washington Quarter was produced at the Philadelphia Mint, marked by the absence of a mint mark, and is part of the standard series that includes various designs over the years. Collectors often seek specific years and mint marks, with certain examples appreciating in value due to limited availability or special features.
