10 Céntimos Castellgalí

Castellgalí is a small municipality in Bages, Barcelona province, with a population that barely reached a few hundred during the 1930s. That a village this size issued its own emergency paper fractional currency during the Civil War is less surprising than it sounds — by 1937, the breakdown of small coinage across Republican-held Catalonia had pushed hundreds of municipalities, many far smaller than Castellgalí, into printing their own local scrip under a framework loosely sanctioned by the Generalitat.

At 40 × 31 mm, this is among the smallest formats in the entire Catalan wartime series. The thick card stock was a practical choice: notes this small had to survive pocket and till handling without disintegrating.
