Liberty Seated Half Dollars were minted in the United States from 1839 to 1891 and are characterized by their depiction of Liberty seated on a rock. The 1875 issue was produced in both Philadelphia and San Francisco, with the San Francisco mint mark "S" indicating its origin. These coins are valued by collectors for their historical significance and unique design features, with varying levels of rarity depending on the specific year and mint. The 50-cent denomination is popular among numismatists, with the San Francisco mint examples often commanding higher prices due to lower mintage and demand.
