Collectible coins, also known as numismatic coins, can vary widely in terms of type, era, and rarity. The United States has a rich history of collectible coins including the 5 Dollar gold coins and Coronet Head Cents minted during the early 19th century. The Coronet Head Cent, produced from 1816 to 1839, features a portrait of Liberty and is sought after by collectors for its historical significance and design. The 1817 variant, in particular, holds interest due to its age and the relatively low mintage compared to other years.
