Collectible coins, often referred to as numismatic coins, encompass a variety of types, including historical, commemorative, bullion, and-error coins. In the United States, collectible coins can range from early colonial coins to contemporary issues, such as the American Eagle or National Park quarters. The DT 20 commonly refers to a specific design or issue from a particular minting year or set that holds significance for collectors, often influenced by factors such as rarity, condition, and demand. Collectors may seek these coins for investment, historical interest, or aesthetic appreciation.
