5 Centimos La Casa del Pueblo

La Casa del Pueblo was a Socialist workers' club, and in the anarchic early months of the Spanish Civil War, hundreds of such local organizations across Republican-held Catalonia issued their own small-denomination emergency notes — céntimos coinage had effectively vanished from circulation, hoarded or melted down. Martorrell, a small town on the Llobregat river southwest of Barcelona, was typical of communities forced into this improvised monetary arrangement.

These hyper-local issues were produced in tiny quantities, often on whatever printing equipment the town possessed. Survival rates are low not through destruction but through simple loss — notes of five céntimos weren't worth saving.
