1/3 Groat - Peter de Portugal Tortosa

Peter of Portugal's brief reign as King of Catalonia — recognized by the Generalitat in 1463 as a rival claimant against John II of Aragon during the Catalan Civil War — produced a small and irregular coinage at Tortosa, one of the few mints that remained under rebel control. His kingship lasted only until his death in 1466, at which point the Catalans offered the crown to René of Anjou, making this a genuinely short-window emission tied to a disputed throne that never achieved broad territorial control.
