1/3 Groat - John II Tortosa

John II of Aragon held Catalonia under duress for much of this period — the principality had deposed his son Charles of Viana in a succession dispute, triggering a civil war that ran from 1462 to 1472. Tortosa, one of the few cities that remained loyal to John throughout the conflict, continued issuing coinage in his name while much of Catalonia backed the rival claimants, including briefly a Castilian king and then René of Anjou.

The Tortosa mint's output during these years was limited by the disruptions of war and the city's relative isolation.
