1873-1878-S US Trade Dollars

The San Francisco Mint Trade Dollar, identified by the "S" mint mark, was struck between 1873 and 1878 as part of the United States' effort to facilitate international trade, particularly with China and the broader Asian market. These coins were minted in large numbers and exported overseas, where they competed with popular silver coins like the Mexican Peso and Spanish 8 Reales.

💡 Historical Significance:

The San Francisco Mint was strategically important due to its proximity to Pacific trade routes. A large portion of S-mint Trade Dollars were shipped to China, where they often received chop marks (small stamped characters from merchants or banks verifying authenticity). These marks are now a collectible aspect of the coin’s history.
