Collectible coins, particularly in the United States, encompass a variety of types, including various denominations like the quarter (P) and fifty-cent pieces (50). Patterns are a specific category of collectible coins, representing trial strikes or experimental designs that were made to test new coins before their official production. These items are highly sought after by collectors due to their uniqueness and historical significance within U.S. coinage. The market for such coins often reflects both rarity and demand, influencing their value among enthusiasts and investors.
