The Capped Bust Quarter, minted from 1815 to 1838, is a notable type of U.S. coin featuring a depiction of Liberty wearing a cap, signifying freedom. The 1831 issue is particularly sought after by collectors due to its historical significance and unique design details. Four-Dollar coins, or gold stella, were never widely circulated but remain a key interest among numismatists, often due to their rarity and distinctive aesthetic. Collectors prize these coins for their artistic value as well as their place in American numismatic history.
