1878-CC

The 1878-CC Trade Dollar is the apex Key Date of the entire circulation-strike series, with a 97,000-piece mintage struck in two months at the Carson City Mint before production halted permanently in February 1878. Carson City delivered 56,000 pieces in January and 41,000 in February, then ceased Trade Dollar coinage entirely after Treasury Secretary John Sherman ordered the halt on February 22, 1878, with the Bland-Allison Act establishing the new Morgan Dollar series later that month. The CC mintmark would never again appear on a Trade Dollar. Treasury records confirm that 44,148 undistributed Trade Dollars at the Carson City Mint were melted on July 19, 1878, with the vast majority being 1878-CC pieces from the February delivery, leaving a net distributed mintage of only 52,852.

Strike quality on the 1878-CC varies, with the brief production window producing both early-die-state and late-die-state examples in the small total mintage. Liberty's head and the eagle's central feathers come up cleanly on most early-die-state coins. Most surviving 1878-CC pieces grade VF to AU from circulation along the western and Asian trade routes, with PCGS, the Professional Coin Grading Service, and NGC populations clustering at VF and EF. Mint State examples are genuinely rare at all levels, with MS63 examples condition-scarce and MS65 and above among the trophy pickups of the Trade Dollar series. Counterfeit 1878-CC examples exist; added-mintmark alterations from genuine S-mint and Philadelphia Trade Dollars and re-engraved date alterations from earlier CC issues are the principal authentication concerns.

The 1878-CC is the recognized Key Date of the Trade Dollar series and the centerpiece pickup for any serious Trade Dollar collection. Pricing trades at premium levels at every grade, with the climb to MS63 substantial and the gap from MS63 to MS65 dramatic. A PCGS MS65 example sold for $192,000 at Heritage in January 2019, establishing the modern price ceiling for the issue. The 1878-CC pairs with the 1873-CC and 1875 as the three principal Semi-Key and Key Date entries that define the upper tier of any complete circulation-strike set. Certified slabs from PCGS or NGC are essential at any meaningful price level.
