1 Sechsling - Ulrich III

Ulrich III ruled Mecklenburg-Güstrow as co-duke alongside his brother Johann Albrecht I following the 1555 partition of the duchy at Güstrow — an arrangement that divided administrative and minting authority between two courts simultaneously. The Sechsling denomination was a small northern German accounting coin, its value pegged to six Pfennig within the Low Saxon monetary system.

Kunzel 129 B/a places this among the better-documented die marriages for the type, though varieties from this reign frequently show inconsistent flan preparation, a known characteristic of the Güstrow mint during the 1560s.
