Collectible coins, also known as numismatic coins, encompass a range of items sought after for their historical significance, rarity, and aesthetic appeal. One notable example is the Capped Bust Quarter, produced in the United States from 1815 to 1838, with the 1818 Philadelphia minting being particularly sought after by collectors. The Capped Bust design features a profile of Liberty wearing a cap, symbolizing freedom, and is known for its intricate details and classic artistry. Collectors often value these coins not just for their face value, but for their historical context and the numismatic value they represent.
