Collectible coins include a variety of types, such as patterns and trial coins. Patterns are experimental coins struck to test designs or compositions before mass production, while trial coins serve similar purposes, often produced in limited numbers. The 1874 fifty-cent coin from Philadelphia is notable as a collectible piece, representing a transitional moment in U.S. coinage. These coins can be highly sought after by collectors due to their rarity and historical significance.
