1/2 Noble - Edward III Post-Treaty period, Calais mint

The Post-Treaty period nobles were struck following the breakdown of the Treaty of Brétigny in 1369, when Edward III formally reasserted his claim to the French throne — a claim he had briefly set aside under the treaty's terms. Calais, England's continental foothold since 1347, operated as a legally mandated staple for wool exports and ran its own mint precisely because the volume of bullion moving through the port justified it.

Spink 1525 half nobles from Calais are distinguished from London issues by their mint mark and pellet arrangements. Die linkage studies by Lawrence and later Blunt and Whitton remain the primary tools for attribution within this series.
