Gros 'Florette' - Henry V of Lancaster

The Gros Florette was already a well-established French denomination when Henry V claimed the right to strike it following his conquest of Normandy in 1419. Minting it was a deliberate political act — by producing French coin types under his own name, Henry asserted not merely military occupation but legitimate hereditary rule over France, a claim he would formalize in the Treaty of Troyes in May 1420, which named him heir to Charles VI.

The Paris and Rouen mints both struck issues during this window. Rouen had only fallen to Henry in January 1419 after a six-month siege during which the civilian population suffered catastrophic famine.
