Seated Liberty Quarters were minted in the United States from 1838 to 1891, featuring an image of Liberty seated on a rock. The 1866 Seated Liberty Quarter is particularly notable, especially if struck in San Francisco, due to its lower mintage and the historical significance of the year following the Civil War. Collectors value these coins for their design, rarity, and condition, with certain varieties commanding higher premiums in the numismatic market.
