The Coronet Head Cent is a type of large cent produced by the United States Mint, with a design first introduced in 1816. The coins, minted in Philadelphia, feature a portrait of Liberty wearing a coronet. The 1816 Coronet Head Cent is of particular interest to collectors due to its historical significance and the limited mintage during that period. Four Dollar coins, or "Stella" coins, were minted as experiments in the late 19th century and are also sought after by numismatists. Collectors often seek these coins for their unique designs and the historical context of their production.
