Collectible coins, particularly in the United States, encompass a wide variety of denominations, including the five cents nickel and the half dime. Patterns and trial coins, such as those produced in Philadelphia in 1860, serve as experimental pieces that test new designs or compositions before full-scale minting. These coins are often highly sought after by collectors due to their rarity and historical significance in the evolution of American currency.
