Charles III 8 Reales

The Charles III 8 Reales was the backbone of 18th-century global trade, circulating from the Philippines to the Carolinas and influencing everything from American colonial currency to Chinese trade dollars.

Struck in Mexico City and other viceregal mints, these silver coins used metal from New World mines, often on planchets that bore traces of earlier mintings. The design featured the Pillars of Hercules framing a crowned shield, with the date and mint mark squeezed into the margins—a practical touch for a coin that traveled far. We know production ran from 1759 to 1788, but exact mintage figures for many years vanished in archival fires or colonial upheavals.

Variations exist, like the 1772 "royal" issue with a bust of Charles, but fakes abound, which keeps us experts busy. As for myths about pirate hoards, let's just say not every worn specimen swam with doubloons.
