⅔ Thaler - Frederick VI

Saxe-Lauenburg was one of the most politically precarious duchies in the German confederation — a tiny territory with a dynastic succession so tangled that Denmark effectively controlled it through personal union for much of the nineteenth century. Frederick VI of Denmark ruled as Duke of Saxe-Lauenburg from 1816 until his death in 1839, coining in that capacity despite the duchy having no meaningful administrative independence. The ⅔ Thaler denomination itself was a North German convention tied to the Reichsthaler system, increasingly obsolete by 1830 as monetary standardization pressure built across the German states.
