6 Mariengroschen

The city of Hildesheim maintained a peculiar monetary independence throughout the later seventeenth century despite sustained pressure from the Prince-Bishopric that surrounded it on all sides. The 6 Mariengroschen denomination was a practical workhorse of Lower Saxon trade, pegged to a regional reckoning system where the Mariengroschen — literally the "Mary's groschen" — served as the dominant fractional unit across Brunswick, Hildesheim, and their neighbors.

The nearly thirty-year striking window for KM#230 suggests dies were reused extensively, and date varieties across this run show considerable inconsistency in execution — not unusual for a civic mint operating without the resources of a territorial prince.
