1 Thaler - Frederick August

Nassau was reorganized as a duchy under Frederick August in 1806, following Napoleon's restructuring of the German states through the Confederation of the Rhine. This thaler belongs to the first years of that new political order — struck just three years after Nassau's elevation, when the duchy was still consolidating its administrative and monetary apparatus under French imperial influence.

The .833 fineness follows the Conventionsthaler standard then being phased across the Rhenish Confederation states.
