Collectible coins, often regarded as numismatic items, can be categorized into various types based on their historical significance, rarity, and condition. In the United States, coins such as the 1794 Silver Dollar are noteworthy for their early minting history and are considered key pieces for collectors. Patterns are experimental coins created to test designs, often limited in number and not intended for circulation, adding to their allure among numismatists. The 1794 Pattern coins represent some of the earliest attempts to establish a national currency, making them highly valued in the realm of collectible coins.
