Cornado - Juan III and Catalina

Juan III and Catalina ruled Navarre jointly as co-monarchs following their marriage in 1484, a dynastic arrangement designed to satisfy both the Navarrese succession and French political pressure from Louis XI's successors. The kingdom was already under severe strain from internal factional conflict — the Agramont and Beaumont parties had been tearing Navarrese politics apart for decades — and French encroachment made independent monetary policy increasingly difficult to sustain.

The billon cornado was the workhorse of small Navarrese commerce, though the kingdom's annexation by Ferdinand of Aragon in 1512 ended the joint reign abruptly, making later dates within this emission range considerably harder to locate.
