1852 Liberty Seated Half Dollar. WB-3. Rarity-4. EF-45 (PCGS). Deep pearl-gray patina with subtle undertones of iridescent gold, powder blue and pale pink. Just 77,130 circulation strike half dollars were produced in the Philadelphia Mint in 1852, the vast majority of which were hoarded and melted by speculators during an era when the precious metal value of old tenor U.S. Mint silver coins exceeded face value. From the Collection of Silas Stanley Roberts, 1888-1966.
