1/4 Thaler - August I

August I consolidated Saxon silver coinage aggressively after inheriting the electorate in 1553, leveraging the enormous output of the Erzgebirge mines — then among the most productive in Europe — to standardize fractional thalers for regional trade. The Joachimsthaler system underpinned this whole enterprise, and Saxony was instrumental in spreading it across the Empire.

MB#190 places this squarely within Keilitz/Kahnt attribution territory. The 1557–1571 span covers the full productive peak of the Annaberg and Schneeberg operations before yield decline set in after 1570.
