Seated Liberty Half Dollars were minted in the United States from 1839 to 1891 and feature a depiction of Liberty seated on a rock holding a Liberty cap and a shield. The 1865 Seated Liberty Half Dollar is particularly significant due to the historical context of the Civil War era. Collectors often seek out these coins for their design, historical value, and varying mintage numbers. The coin is made of 90% silver and 10% copper, which contributes to its appeal among numismatists.
