Collectible coins, often referred to as numismatic items, include a wide range of pieces that are sought after by collectors for their historical significance, rarity, and craftsmanship. In the United States, collectible coins such as the One Dollar coin have various designs and denominations, with notable examples like the Coronet Head Cent, which was minted from 1816 to 1857. The 1823 Coronet Head Cent, in particular, is recognized for its distinctive Liberty portrait and can vary in value based on condition, rarity, and demand among collectors.
