71/2 Batzen Siege coinage, Klippe

Frankenthal, a Palatinate town garrisoned by Dutch troops, endured a prolonged siege during the early Thirty Years' War. The 1623 klippe was struck from whatever silver could be gathered inside the walls — siege coinages of this type were emergency authorizations, not planned issues, and the irregular square planchet reflects exactly that: speed over precision. Frankenthal finally surrendered to Spanish forces in April 1623, making this issue datable to the final weeks of the siege itself.
