1872-CC Liberty Seated Silver Dollar. OC-1, the only known dies. Rarity-3+. EF-40 (PCGS). Brilliant and boldly defined overall, with plenty of bright mint luster evident as the surfaces rotate under a light. The 1872-CC boasts a paltry mintage of 3,150 pieces, survivors of which number only 250 to 300 coins in all grades (per Rusty Goe, 2020). It is the third rarest of only four Carson City Mint issues in the challenging Liberty Seated dollar series of 1840 to 1873. PCGS# 6969. NGC ID: 24ZK.
