Cornado - Juan II

Juan II of Navarre held the kingdom largely through his wife Blanca I, whose death in 1441 triggered a dynastic civil war between Juan and his own son Carlos de Viana that consumed Navarre for decades. This small billon cornado circulated through that conflict — a war in which the French crown, Castile, and Aragon all intervened at various points, reducing Navarre to a pawn rather than a sovereign player.

The billon content of these issues degraded noticeably across the emission period as fiscal pressure mounted.
