Collectible coins, particularly from the United States, encompass a variety of types including the five cents nickel and half dime denominations. The Seated Liberty Half Dime, minted from 1837 to 1873, features a design representing liberty seated on a rock. The 1839 issue, particularly those minted in New Orleans, is notable for its unique characteristics and lower mintage, making it more sought after by collectors. These coins are significant not only for their numismatic value but also for their historical context within American currency.
