1/2 Kreuzer - Frederick William III

Prussia had no business minting half kreuzers. The kreuzer was a South German denomination — Bavaria, Baden, Württemberg territory — and its appearance under Frederick William III reflects the administrative chaos following Prussia's absorption of Ansbach and Bayreuth from Bavaria in 1792. Local populations expected local money, and Berlin obliged, briefly, before Jena changed everything.

1806 is the last year of this type. Napoleon's decisive victory at Jena-Auerstedt in October of that year effectively ended Hohenzollern control over their Franconian territories, rendering further production pointless.
