Weiss-Pfennig - Ferdinand I D.G.EL.RO.IMP

Ferdinand I secured the Bohemian crown in 1526 largely through his marriage to Anne of Bohemia and Hungary, but his grip on the kingdom was never unchallenged — a Protestant-backed revolt in 1547 forced him into a prolonged renegotiation of Bohemian noble privileges. These tiny silver pfennigs, struck in the closing years of his reign before his death in 1564, represent the tail end of a 38-year rule that reshaped Central European Habsburg consolidation. The multiple Donebauer references reflect genuine die variation across the issue, not mere cataloguing redundancy.
