Collectible coins include a wide range of pieces sought after by numismatists, which can include historical coins, error coins, and limited edition releases. The "Five Dollar" denomination in the United States often refers to gold pieces, particularly the Liberty Head or Indian Head designs. The Coronet Head cents were minted from 1816 to 1839 in Philadelphia and are known for their iconic Liberty portrayal. The 1817 Coronet Head cent is particularly valued by collectors for its historical significance and scarcity.
