Collectible coins, particularly from the United States, can encompass a variety of types, including territorial coins. The term "territorial" refers to coins minted in U.S. territories before they became states. An example is the twenty-dollar coins struck in 1861. These coins are significant due to their historical context and rarity, with some remaining examples being unknown or unreported, adding to their allure among collectors. The value of collectible coins is influenced by factors such as rarity, condition, and historical importance.
