25 Céntimos Vall de Castellbó

Vall de Castellbó is a tiny municipality in the Alt Urgell comarca of Catalonia, and this 25 céntimos note is one of thousands of hyperlocal emergency issues produced during the Spanish Civil War — the so-called "Guerra Civil" vales that flooded Catalonia after the Republican government authorized municipalities to issue their own small-change substitutes in 1936 and 1937, when coinage effectively vanished from circulation. The Turró catalogue remains the primary reference for these Catalan municipals, and Vall de Castellbó's issues are among the more obscure entries given the village's minimal population.

Thick card stock was the norm for the smallest-denomination rurals — cheaper to produce locally and harder to counterfeit than thin banknote paper.
