Collectible coins, often referred to as numismatic items, can include various types such as historical coins, commemorative coins, and bullion coins. The United States has numerous collectible coins, including the $5 Coronet Head gold pieces minted in the 19th century. The Coronet Head design was used from 1813 to 1839, with the 1819 Philadelphia minting being notable for its historical significance. Collectors often seek these coins for their rarity, condition, and the stories they tell about the era in which they were produced.
