1 Thaler - Frederick William III

Frederick William III came to the Prussian throne in November 1797 already inheriting a kingdom financially exhausted by the Revolutionary Wars and diplomatically squeezed between France and Russia. This thaler was struck through one of Prussia's most humiliating decades — the catastrophic defeat at Jena-Auerstedt in 1806 reduced the kingdom to a French satellite state, and Napoleon's Continental System disrupted the silver trade routes that had long supplied the Berlin and Breslau mints. The .750 fineness reflects a deliberate reduction from earlier Prussian thaler standards, a quiet acknowledgment of fiscal strain that the court preferred not to announce openly.
