3 Kreuzers - Frederick Ulrich Kipper

Frederick Ulrich's 3 Kreuzer belongs to the Kipper und Wipper crisis of 1619–1623, arguably the most catastrophic currency debasement in German history before the twentieth century. Territorial mints across the Holy Roman Empire — Brunswick-Wolfenbüttel among them — raced to produce debased small coinage, exchanging it for full-weight silver before neighboring states could react. The profit motive was explicit: mint lessees paid the duke for the right to operate and pocketed the difference between face value and bullion cost.

Frederick Ulrich himself was a weak ruler, and the Kipper operation at his mints was largely driven by financial officials rather than ducal initiative. The crisis collapsed when too many states simultaneously refused the coins.
