Collectible coins can be classified into various categories, including patterns, commemoratives, and bullion. Patterns are a specific type of collectible coin that were created as experimental designs or prototypes before official minting. The 1869 pattern coins, for instance, represent a significant numismatic interest, as they often showcase unique designs that were not adopted for regular circulation. These coins can hold considerable historical value and appeal to collectors of United States minting history.
