Collectible coins include a variety of types, among which are patterns and trial coins. Patterns are experimental pieces created to test new designs or compositions, often struck in limited numbers. The 1838 U.S. dime, or ten cents piece, is notable as it marks the first year of issue for the Seated Liberty design. These trial coins can hold significant historical value due to their rarity and involvement in the evolution of American coinage.
