60 Kreuzer 'Sortengulden' - Damian Hartard of the Leyen

Damian Hartard von der Leyen's brief archiepiscopate coincided with the monetary chaos following the Thirty Years' War, when the Holy Roman Empire's coinage system remained deeply fragmented. The 60 Kreuzer denomination — the so-called Sortengulden — emerged as a practical response to that fragmentation, pegged nominally to facilitate trade between territories using incompatible reckoning systems. Mainz, as one of the three ecclesiastical electoral states, carried unusual political weight in enforcing or ignoring imperial monetary conventions, and frequently did the latter.

The two-year window of this issue reflects Damian Hartard's death in 1675, making surviving examples from the full run relatively scarce.
