150 Kipper Kreuzers / Kipper Thaler - Ferdinand II Neisse or Olmütz

The Kipper und Wipperzeit — the "tipper and see-saw time" — was a currency crisis running roughly 1619 to 1623 in which mints across the Empire raced to debase coinage, clipping silver content while maintaining face value to fund the opening campaigns of the Thirty Years' War. Ferdinand II, despite being the imperial authority nominally responsible for monetary order, was among the worst offenders; his Silesian and Moravian mints at Neisse and Olmütz struck vast quantities of debased Kipper coinage to pay troops and service war debts. The 150 Kreuzers denomination itself is a creature of this crisis — a face value so inflated it had no peacetime precedent.

Attribution between the two mints remains contested, which accounts for the paired reference in Herinek.
