⅔ Thaler - George III

By 1801, Brunswick-Lüneburg-Calenberg-Hannover occupied an awkward constitutional position: George III was its Elector while simultaneously serving as King of Great Britain, a personal union that had persisted since 1714. The ⅔ Thaler denomination itself was a North German convention rooted in the Zinna monetary convention of 1667, which established the 2/3 Thaler — equivalent to the Gulden — as a workable fraction for regional trade. Napoleon's campaigns were already reshaping the German states around Hannover at precisely the moment these coins were struck, and French occupation of the Electorate followed in 1803, effectively suspending Hanoverian coinage for years.
