1 Kronenthaler - William

The Kronenthaler was a supra-regional trade coin whose value was fixed by convention across multiple German states rather than by any single issuing authority — Nassau's participation in striking them reflected the monetary agreements hammered out among the Rhine Confederation successor states in the 1820s. William of Nassau-Weilburg had come to power in 1816 presiding over a duchy assembled from fractured Napoleonic-era territorial reshuffling, and the Kronenthaler issues of his later reign were among the last struck before the type was phased out across the German states by the mid-1830s Dresden Convention push toward standardized coinage.
