Denier - Baldwin IV / Baldwin V Bruges

This denier belongs to a prolonged and historically murky joint attribution covering nearly eight decades of Flemish comital coinage — a span that includes Baldwin IV's aggressive territorial expansion southward into imperial Hainaut and his son Baldwin V's consolidation of those gains through strategic marriages and regency over the young French king Philip I. The Bruges mint was the commercial heart of the county, positioned on trade routes feeding the North Sea cloth economy.

Distinguishing Baldwin IV issues from Baldwin V within this type remains a problem the Ilisch classification only partially resolves.
