10 Batzen

Solothurn's 10 Batzen denomination occupied an awkward position in mid-18th century Swiss monetary circulation, where the Batzen itself was a unit of fluctuating local value across cantons — what passed for 10 Batzen in Solothurn did not necessarily equate to the same purchasing power across the Aare into Bern. The city's mint operated under the authority of the cantonal council, which jealously guarded its coinage rights even as larger Swiss powers pushed intermittently for regional standardization.

Production ran only three years, suggesting either a satisfied immediate demand or a council decision to halt further expense. The HMZ reference places this cleanly within Solothurn's documented cantonal series.
