1873-S

The 1873-S Trade Dollar is the inaugural San Francisco issue of the series and the largest 1873 production at 703,000 pieces, reflecting the role of the San Francisco Mint as the primary export gateway for U.S. silver bound for Asia. The Coinage Act of February 12, 1873 authorized the new 420-grain silver coin specifically for use in commercial trade with China and Japan, and San Francisco production scaled up immediately to supply Pacific shipping routes. The 1873-S carries the Type I obverse and Type I reverse hubs that define the series through 1875, with the S mintmark positioned below the eagle on the reverse.

Strike quality on the 1873-S is generally above average for the date, with Liberty's head and the eagle's central feathers coming up cleanly on most early-die-state coins. Most surviving 1873-S Trade Dollars grade VF to AU from heavy circulation in Pacific Coast and Asian commerce, with PCGS and NGC populations clustering at EF and AU. Mint State examples are scarce above MS62 and condition rare at MS65 and above. Chopmarked examples, where Chinese merchants stamped the coin with authentication characters, are relatively common for 1873-S because of the heavy Asian trade routing and are catalogued separately from clean-surface examples by major grading services.

The 1873-S is a regular common date and a fundamental first-year San Francisco pickup for any Trade Dollar collection. Pricing trades at small premiums above the larger 1875-S, 1876-S, and 1877-S mintages at most circulated grades, supported by first-year-of-issue demand. The 1873-S pairs with the 1873-P and 1873-CC as the matched inaugural-year trio that opens the Trade Dollar series. Certified slabs from PCGS or NGC are the standard purchase route at higher grades given the prevalence of cleaning and polishing in the raw market.
