1 Vereinsthaler - Francis Joseph I

The Vereinsthaler was the product of the Dresden Coinage Treaty of 1838, later reinforced at Vienna in 1857, which bound the German states and Austria to a common large-silver denomination for cross-border trade. Austria's participation was always uneasy — the Vienna Mint struck these to satisfy treaty obligations while the empire simultaneously managed a separate domestic currency system. The years 1866–1868 bracket one of the most consequential defeats in Habsburg history: the loss to Prussia at Königgrätz in July 1866 effectively ended Austrian influence over the German states, and with it any future in the Vereinsthaler framework.

Austria formally withdrew from the German Monetary Union shortly after, making these among the last Vereinsthaler struck at Vienna under treaty compulsion.
