Seated Liberty Half Dollars are a series of coins minted in the United States from 1839 to 1891, featuring a design by engraver Christian Gobrecht. The 1870 issue is particularly significant due to its limited mintage and historical context. These coins depict Lady Liberty seated, with various motifs surrounding her, embodying the ideals of liberty and freedom. They are sought after by collectors for their intricate design and the role they play in U.S. numismatic history, especially among those specializing in the Fifty Cents denomination.
