1 Thaler - Frederick II Conventionsthaler

Frederick II ruled Württemberg as Duke until Napoleon's reorganization of German territories under the Confederation of the Rhine elevated him to King in 1806 — making this 1803 piece one of the final issues struck under his ducal authority, just three years before that transformation. The Conventionstaler standard itself, established by the 1753 Munich Convention between Austria and Bavaria, was already being undermined by Napoleonic-era monetary disruption when this coin left the dies.

Württemberg's elevation came at a price: Frederick supplied troops to Napoleon's campaigns and ceded significant territorial autonomy in exchange for his crown.
