Groat 'with Lion' - William II of Avesnes

William II of Avesnes — better known as William IV of Holland — issued this groat during the years he was simultaneously managing a war against the Frisians and navigating his county's relationship with Edward III of England, whose wool trade depended heavily on Flemish and Hainaut neutrality. William died in 1345 at the Battle of Stavoren, drowned in the Zuiderzee after his forces were routed by the Frisians, leaving no male heir and triggering the prolonged War of the Bavarian Succession over Holland and Hainaut.

The four-year window of this issue reflects a mint policy tied directly to William's fluctuating alliances rather than any administrative reform.
