4 Ducats - Johann Jakob Khuen von Belasi

Johann Jakob Khuen von Belasi served as Archbishop of Salzburg from 1560 until his death in 1586 — the same year this coin was struck, making it almost certainly a late-reign or posthumous issue. His tenure coincided with the most aggressive phase of Counter-Reformation policy in the region, and the archbishopric's mint was active in producing prestige multiples as diplomatic gifts and display pieces for the Catholic nobility. Four-ducat strikes of this period were never intended for commercial circulation.

The Probszt reference places this among a small group of documented high-denomination Salzburg gold issues from the 1580s.
