1 Goldgulden - Jakob I of Sierck

Jakob I von Sierck held the archbishopric of Trier from 1439 to 1456, but his early years in office were consumed by the broader crisis of the conciliarist movement — the schism between Pope Eugene IV and the Council of Basel had fractured ecclesiastical authority across the Rhineland, and Rhenish princes including Jakob initially backed the Basel faction. The goldgulden issues of 1439–1443 fall squarely within this turbulent alignment period, when the Archbishop's political positioning was still unsettled.

Trier's Rhine goldgulden production through this period fed into the dense circulation network of the Kurrheinischer Münzverein, the electoral Rhenish mint union.
