⅔ Thaler - George I

The ⅔ Thaler denomination — equivalent to the Gulden and therefore sometimes called the Gulden-Thaler — was the workhorse of north German silver coinage throughout the late seventeenth and early eighteenth centuries, its fractional relationship to the Thaler making it practical for large transactions without requiring full Thaler weight. George I's accession to the British throne in 1714 created an unusual administrative situation: Brunswick-Lüneburg continued striking coins in his name under the authority of the Hanoverian mint well after he had ceased to govern the territory in any practical daily sense.

The KM#112.1 and #112.2 distinction reflects a die variation in the mintmaster's mark, not a substantive change in type.
