Collectible coins are typically categorized based on their historical significance, rarity, and condition. The United States has produced various denominations, including the five-cent nickel and the half dime. The Seated Liberty design, which includes both half dimes and other denominations, was minted from the mid-1800s to the late 1800s, with the 1855 Philadelphia mint mark being a noteworthy year for collectors. The half dime, which was used before the nickel became more widely circulated, features themes of liberty and is popular among numismatists for its aesthetic appeal and historical context.
