Collectible coins, particularly those from the United States, encompass a variety of series and types, including the One Dollar coins. The term "patterns" refers to experimental coins created to test new designs or compositions before official minting, with many being produced in small quantities. One notable example is the 1916 One Dollar pattern coins, which feature distinctive designs that reflect artistic trends of the era and are highly sought after by collectors due to their rarity and historical significance.
