1 Goldgulden - Albert and Charles I

Münsterberg-Oels was a minor Silesian duchy that changed hands repeatedly among the Piast and then Poděbrady lines before passing to the Habsburgs. Albert and Charles I ruled jointly — a co-rulership arrangement that was itself a product of dynastic negotiation rather than succession in the ordinary sense. Joint-rule coinages from Silesian duchies of this period are notoriously difficult to attribute cleanly, and the 1510–1512 window for this issue reflects the brief overlap of their shared administration before the duchy's absorption into a broader Habsburg territorial consolidation.
