The 18 Kreuzer denomination was produced at Breslau during the First Silesian War's aftermath, when Frederick II exploited Silesian mint infrastructure to fund ongoing military campaigns. These coins were explicitly designed for circulation in Silesia and adjacent territories — denominations calibrated to local Austro-Hungarian monetary conventions rather than Prussian ones, a deliberate policy of monetary assimilation following the 1742 annexation.
Frederick's Silesian subsidiary coinages have a complicated numismatic reputation. Several issues from this period were produced well below their stated silver content, effectively functioning as debased trade coins. The KM#969.1 distinction separates die varieties by mintmaster mark.
