Collectible coins refer to numismatic items that hold value beyond their face value, often due to rarity, historical significance, and condition. In the United States, the five cents nickel and half dime, particularly the Seated Liberty Half Dime, are notable examples. The Seated Liberty design was used from 1837 to 1891, with the 1851 issue struck in New Orleans being particularly sought after by collectors due to its lower mintage and the historical context of that era. Collectors often seek coins based on their age, mint mark, and specific characteristics, which can greatly influence their market value.
