25 Céntimos Aínsa

Aínsa is a small Aragonese town in the Pyrenean foothills, and like hundreds of Spanish municipalities during the Civil War, it issued its own fractional paper currency when coinage disappeared from circulation almost entirely after 1936. The Republican government's inability to maintain a functioning small-change supply forced this improvisation at a purely local level — these notes were valid only within the issuing municipality and had no standing elsewhere.

The printer, El Secretariat Català in Barcelona, produced emergency selos de cartón and paper fractionals for numerous Aragonese and Catalan municipalities during this period, which accounts for a certain consistency of production quality across what were otherwise hyper-local issues.
