20 Ducat - John George I

John George I of Saxony was among the most powerful Protestant princes in the Empire, yet his foreign policy during the Thirty Years' War was notoriously cautious — he delayed siding with Sweden until Gustavus Adolphus forced his hand just months before Breitenfeld in 1631. The 1628 date places this piece squarely in the war's most uncertain phase, when Wallenstein's imperial armies were at peak strength and Saxon neutrality was under constant pressure.

Multiple-ducat presentation pieces of this scale were struck at Dresden not for circulation but as diplomatic gifts and treasury demonstrations. At twenty ducats' worth of nearly pure gold, this was a deliberate show of electoral wealth during a period when Saxon finances were being tested by war contributions and troop quartering.
