1 Mariengroschen - Ulrich VI

Regenstein was among the smallest and most financially marginal counties in the Harz region, and by the 1540s the comital line was effectively on borrowed time — Ulrich VI would prove to be among its last rulers before the county passed to Brandenburg-Prussia through inheritance and debt. The Mariengroschen denomination itself was a north German workhorse, adopted across dozens of small Harz and Lower Saxon territories precisely because its value was legible across jurisdictional borders in a region fragmented into scores of competing mints.

Schultze 2886 is known from very few die pairs, consistent with a short and administratively constrained minting episode.
