1840 Liberty Seated Silver Dollar. OC-2. Rarity-4+. Repunched Stars. AU-55 (PCGS). Pretty undertones of iridescent powder blue, antique gold and pale pink backlight dominant antique silver and olive-gray patina. Both sides are sharply struck with plenty of lively mint luster remaining. The 1840 Liberty Seated dollar is surprisingly elusive in all grades for a first year issue in U.S. coinage history, and this endearing coin is better preserved than most survivors. The OC-2 attribution adds further appeal for the specialist, the variety identifiable by repunching to stars 6 through 8.
