1 Sobirana - Joan Martí i Alanis Episcopal Co-Prince, Catalan

Andorra issued its first domestic coinage only in 1976, after centuries of operating almost entirely without native-struck money — transactions had long been conducted in French francs and Spanish pesetas under the diarchic arrangement shared between the French head of state and the Bishop of Urgell. Joan Martí i Alanis, who held the episcopal co-princeship from 1971 to 2003, appears on this early issue as one of two sovereign authorities, a feudal structure dating to the 1278 Paréage agreement between the Count of Foix and the Bishop of Urgell.
