1 Duit

Kampen's municipal coinage authority was a jealously guarded privilege, and by the mid-seventeenth century the city was one of the last of the old Hanseatic towns still exercising independent copper coinage rights in the northern Netherlands. The duit was the workhorse denomination of small daily commerce — toll payments, market transactions, alms — and Kampen continued issuing its own well after neighboring cities had ceded that function to the provincial mints of Overijssel.

CNM 2.30.80 places this squarely within a documented sequence of municipal issues from the 1640s, a decade when Kampen was navigating economic marginalization relative to the dominant Dutch trading cities to its west.
