Leopard d'Or - Edward III

Edward III struck these for Aquitaine following the Treaty of Brétigny in 1360, which handed him full sovereignty over the duchy — no longer held as a French fief, but as an outright possession. The timing matters: this was the high-water mark of English territorial ambition in France, and the coinage was part of a deliberate assertion of independent lordship over the region.

The Black Prince administered Aquitaine from 1355 onward, and the political administration behind these coins was largely his.
