20 Centimos La Casa del Pueblo

During the first weeks of the Spanish Civil War, the collapse of small-denomination coinage in Republican-held territory forced hundreds of local entities — trade unions, municipal councils, cooperatives — to print their own emergency scrip. La Casa del Pueblo in Martorell was the local seat of the UGT, the socialist trade union federation, and its issue of 20 céntimos was purely functional: something to make change when the peseta system had effectively seized up at the small end.

These hyper-local Catalan wartime issues were produced in tiny runs, often on whatever paper and printing equipment was at hand. Survival rates vary wildly, and many types are known from fewer than a handful of examples.
