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

The Post-Treaty period designation marks a specific political rupture: Edward III's formal resumption of the French royal title in 1369, abandoning the terms of the Treaty of Brétigny signed nine years earlier. That treaty had required him to renounce his claim to France in exchange for full sovereignty over Aquitaine — a bargain that ultimately collapsed when Charles V began systematically undermining English lordship in the south.

The Calais mint was established precisely because England held the town as a staple port for wool exports, giving the crown both the bullion supply and the commercial rationale to strike there continuously from 1363. Dies for Calais issues are distinguishable from London by a small mark of distinction, a detail that attracts considerable specialist attention within this type.
