2 Mariengroschen - Frederick William of Westfalen

The Bishopric of Hildesheim spent much of the Seven Years' War (1756–1763) in an acutely difficult position — Hanoverian and Prussian forces repeatedly moved through its territory, and the local economy bore the strain of military requisitioning and debased emergency coinage circulating throughout the region. This 2 Mariengroschen, struck in the war's final year under Friedrich Wilhelm von Westphalen, belongs to a period when the bishopric was scrambling to reassert fiscal normalcy before the Peace of Hubertusburg formally ended hostilities in February 1763.

The Mariengroschen was a denomination with deep roots in Lower Saxon ecclesiastical coinage, named for the Virgin and long associated with northern German church territories.
