15 Céntimos Castelltersol

Castellterçol is a small municipality in the Moianès comarca of Barcelona province, and like hundreds of Catalan and Spanish towns during the Civil War, it issued its own fractional paper currency when Republican-zone coinage disappeared almost entirely from circulation by 1937. The Generalitat de Catalunya authorized local emergency issues, but quality and accountability varied enormously from one ajuntament to the next.

The 15 céntimos denomination is among the more unusual fractional values chosen — most towns defaulted to 25, 50, and 1 peseta. Its appearance here suggests a specific need to replicate the old 15-céntimo postal or transit denomination.
