2 Mariengroschen - Frederick II

Frederick II of Prussia absorbed East Frisia in 1744 following the extinction of the Cirksena dynasty, and the territory's coinage immediately became a contested administrative matter — Berlin wanted uniformity, but local monetary customs and trade patterns along the North Sea coast demanded continued small-denomination silver issues in familiar regional types. The Mariengroschen denomination was a fixture of Lower Saxon and northwestern German commerce, and suppressing it outright would have disrupted everyday exchange in the markets of Emden.

Production of East Frisian types under Prussian authority was short-lived. By the mid-1750s, Seven Years' War pressures redirected mint priorities entirely.
