The 1831 Capped Bust Quarter is a notable collectible coin minted in Philadelphia, part of the Capped Bust series produced from 1815 to 1838. This quarter features an obverse design depicting Lady Liberty with a capped head, symbolizing freedom, while the reverse showcases an eagle with a shield, a common motif in U.S. coinage. The 1831 issue is particularly valuable due to its lower mintage and historical significance, appealing to both numismatists and collectors of early American currency. Its condition, rarity, and market demand significantly impact its value.
