Dinero 'Cornado' - Alfonso XI Leon

Alfonso XI struck these billon dineros during a reign defined by relentless military pressure on the Nasrid frontier. His decisive victory at the Battle of Río Salado in 1340 — the last major Marinid landing on Iberian soil — was partly financed through aggressive currency debasement, and the cornado issues of this period reflect that fiscal strain in their declining silver content. The type continued unchanged until Alfonso's death at the siege of Gibraltar in 1350, when the Black Death took him before the walls he never breached.
