Pataca of Maria II in Macao

The most intriguing fact about the Pataca of Maria II is that it was struck in Macao using silver planchets recycled from Spanish eight reales, a practical solution to currency shortages in a distant colony.

This coin, denominated at 10 Macao patacas or sometimes 960 reis, bore the queen's portrait on the obverse and a simple coat of arms on the reverse. Minting occurred sporadically between 1835 and 1853, likely at the Macao mint, though exact locations remain unclear due to poor record-keeping. We know the dies were shipped from Portugal, but whether they arrived intact is anyone's guess.

Design-wise, the coin's edges were reeded to deter clipping, a common fraud in the era. Mintage figures? Lost to time, probably in one of the fires that plagued the region.

If you handle one, note the wear on high points; these circulated heavily in trade routes. As for myths about hidden treasures, I've heard enough.
