⅙ Reichsthaler - Frederick William III

Frederick William III issued this denomination during the most turbulent stretch of Prussian history since the Thirty Years' War. Napoleon had shattered the Prussian army at Jena-Auerstedt in 1806, occupied Berlin, and extracted punishing reparations under the Treaty of Tilsit — reparations that drained the treasury and forced Prussia into aggressive monetary reorganization. The coinage reforms of 1809 were partly a consequence of that fiscal emergency.

The wide reference spread across Schrocke numbers and multiple Olding varieties reflects genuine die proliferation across the Berlin and Breslau mints during this span, not collector cataloging enthusiasm.
