1 Mariengroschen

The Mariengroschen was a north German denomination whose name derived from the Virgin Mary, widely used across Lower Saxony and neighboring territories from the late medieval period onward. Hannover's civic coinage of the 1660s was struck during a period when the city retained independent minting rights that would gradually erode as the surrounding Duchy consolidated power — the Duchy of Calenberg-Grubenhagen had already absorbed much of the region's political authority, and the city's autonomous issues were becoming administratively inconvenient.

BuckMeier 255 is the standard reference for this type among collectors of Lower Saxon civic coinage.
