1/2 Groat 1/2 Leeuwengroot - William V

William V, Count of Holland, suffered a severe mental breakdown in 1357 — just three years after this coin was struck — and was confined by his own sister Margaret, who assumed regency and effectively ended his rule. The political instability surrounding his reign was significant enough that his coinage output was limited and irregular. The leeuwengroot denomination itself was a Flemish-influenced type that circulated widely across the Low Countries trading networks, making survivors difficult to attribute to specific short-window reigns with confidence.

Van der Chijs 6#9.10 is among the scarcer William V attributions in the series.
