Collectible coins encompass a variety of types, including patterns and trial coins. The United States has a significant history of producing trial coins, known as patterns, which are created to test new designs or coinage techniques. One notable example is the 1838 five-dollar pattern coin, struck in Philadelphia, which was part of a series intended to finalize the design of gold coins. These collectible items are sought after for their historical significance, rarity, and unique designs.
