1 Ducat - John Kaspar of Ampringen

John Kaspar of Ampringen served as Grand Master of the Teutonic Order from 1664 until his death in 1684, a period when the Order had long since lost its military and territorial relevance in the Baltic and functioned largely as a German noble institution with scattered estates in the Holy Roman Empire. Ducats of this type were struck at the Order's mint in Mergentheim — its administrative seat after the loss of Prussia — and circulated primarily as prestige pieces rather than commercial currency.

Prokisch's census of Teutonic Order coinage notes this as a relatively scarce emission within Ampringen's tenure.
