Collectible coins encompass a wide range of types, often categorized by their historical significance, rarity, or unique characteristics. The United States, for instance, has a diverse array of collectible coins, including the Half Penny, which was used during the early post-Declaration period around 1778. Such coins may have varying levels of availability and condition, with some being relatively unknown or less documented in numismatic literature, thereby affecting their market value and desirability among collectors.
