1878-S

The 1878-S Trade Dollar carries a 4,162,000-piece mintage and represents the final year of San Francisco Trade Dollar production, closing the branch-mint Trade Dollar coinage that had supplied the Pacific Coast and Asian export trade since 1873. San Francisco production continued through 1878 even after the Bland-Allison Act of February 1878 redirected Treasury silver purchases toward the new Morgan Dollar series, with the 1878-S output absorbing remaining branch-mint Trade Dollar die inventory. The S mintmark sits below the eagle on the Type II reverse that defines the post-1876 series.

Strike quality on the 1878-S is generally average for the date, with Liberty's head and the eagle's central feathers coming up cleanly on early-die-state coins but softer on later strikes from the heavy production run. Most surviving 1878-S Trade Dollars grade VF to AU from heavy circulation in Pacific Coast and Asian commerce, with PCGS, the Professional Coin Grading Service, and NGC populations clustering at EF and AU. Mint State examples are scarce above MS62 and condition rare at MS65 and above. Chopmarked examples are common for 1878-S because of the heavy Asian trade routing and are catalogued separately from clean-surface examples.

The 1878-S is a regular common date and one of the more accessible Trade Dollars in mid-grade. Pricing trades at the standard S-mint Trade Dollar level with no meaningful premium over the 1876-S and 1877-S issues. The 1878-S pairs with the 1878-CC as the matched final-year branch-mint Trade Dollar pair, with the Key Date 1878-CC standing as the centerpiece of the year and the common-date 1878-S providing the accessible mid-grade companion. Certified slabs from PCGS or NGC are the standard purchase route at higher grades.
