1 Thaler - Joseph I Breslau

Joseph I became Holy Roman Emperor in 1705 following the death of his father Leopold I, and the Breslau mint — operating under Habsburg authority in Silesia — issued thalers throughout his reign as part of routine provincial coinage. His reign coincided almost entirely with the War of the Spanish Succession, which strained imperial finances considerably and kept Silesian mints active supplying military expenditure. Breslau had been a Habsburg mint town since the late sixteenth century, its output consistently heavier in silver than many imperial counterparts owing to Silesia's proximity to productive Bohemian mining regions.

Joseph died in 1711 at thirty-two, cutting the reign to six years.
