Capped Bust Quarter coins were minted in the United States from 1815 to 1838, featuring a design by engraver John Reich. The obverse depicts a bust of Liberty wearing a cap, and the reverse features a heraldic eagle. The 1815 Philadelphia minting specifically is significant due to its historical context and relative rarity, making it a sought-after collectible among numismatists. Collectors often focus on factors such as mint mark, condition, and overall design when assessing the value of these coins.
