30 Groschen - John George I

The 30 Groschen denomination was a product of the Kipper- und Wipperzeit — the currency crisis of 1619–1623 in which dozens of German minting authorities, Saxony included, systematically debased their coinage to profit from arbitrage against full-weight imperial standards. John George I initially resisted but ultimately participated, authorizing emergency issues that flooded the market with underweight silver. The resulting inflation collapsed wages and food prices across the Holy Roman Empire with a severity that preceded the full devastation of the Thirty Years' War by only months.

Rah/Kr#438 places this piece within a documented series of short-lived Saxon emergency denominations, most of which saw negligible circulation before being demonetized under the imperial remediation edicts of 1623.
