1870-CC Liberty Seated Half Dollar. WB-2. Rarity-5. Large CC. VG Details--Cleaned (PCGS). As the first half dollar issue from the Carson City Mint, most of the 1870-CCs spent years in circulation before securing collector value. As a result, survivors are very scarce and are usually well circulated such as this example. Even despite the wear, Carson City specialists will certainly take notice of this lot.
