1 Oord - Jobst Maximilian multi-fold arms

Gronsveld was a tiny imperial lordship wedged between Maastricht and Aachen, and its counts exploited their minting rights aggressively throughout the Thirty Years' War period — a time when small copper fiduciary coinage circulated far beyond its nominal territory simply because hard metal was scarce. Jobst Maximilian von Bronckhorst-Batenburg held the county from 1617 until his death in 1662, an unusually long tenure that explains the wide date range attributed to this type.

The KM#12 variety designation flags meaningful die differences within the series, likely reflecting multiple contracts with different engravers over four decades of intermittent production.
