1 Groat - Arnold V Tournois castle

Arnold V ruled Loon during a period when the county was under increasing pressure from the Prince-Bishopric of Liège, which ultimately absorbed it upon his death in 1323 — he died without a male heir, and the county passed directly to Liège by prior agreement. This groat was struck against that backdrop of a dynasty visibly running out of time.

The Tournois type derives from the French gros tournois of Louis IX, first struck in 1266, which became the dominant silver denomination template across the Low Countries within a generation. Arnold's adoption of the type reflects how thoroughly French monetary models had displaced local traditions in the region by the late thirteenth century.
