1 Goldgulden - Frederick III of Saarwerden

Frederick III of Saarwerden held the archbishopric of Cologne for over four decades — an unusually long tenure that coincided with the Western Schism, during which he navigated shifting allegiances between rival claimants to the papal throne. The Rhine ecclesiastical electors were among the most politically consequential coin-issuers of the late medieval period, and Cologne's goldgulden circulated far beyond the archdiocese as a trading currency across the lower Rhine basin.

The type follows the Rhenish goldgulden standard established by the Kurverein of 1386, which fixed weight and fineness among the four electoral mints to stabilize regional commerce after decades of debasement disputes.
