⅔ Thaler - Frederick August I

The 2/3 Thaler denomination — equivalent to the Gulden — dominated German silver coinage in the late 17th and early 18th centuries largely because of its convenient alignment with the Reichsgulden standard established at the 1690 Leipzig Convention. Saxony was among the most prolific issuers, and Frederick August I had particular reason to maintain a credible silver coinage: his election as King of Poland in 1697 required enormous cash outlays in bribes to the Polish nobility, funded substantially through Saxon mint revenues.

The 1708–1710 window falls squarely within the disruptions of the Great Northern War, when Swedish military pressure on Polish and Saxon territories strained the Dresden treasury.
