30 Groschen - John George I

The 30 Groschen denomination was a creature of the Kipper- und Wipperzeit — the "clipper and see-saw" inflation crisis that convulsed the German states between roughly 1619 and 1623. Mints across the Empire, including those operating under John George I's authority, debased coinage aggressively to profit from the arbitrage between metal value and face value, flooding circulation with underweight silver pieces. Saxony was among the more prolific offenders despite John George's later attempts to distance himself from the scandal.

The Rah/Kr 559h variety places this within a tightly documented sequence of electoral Saxon issues from that chaotic window.
