1 Peseta Grañén

Grañén is a small municipality in the province of Huesca, Aragon, and like hundreds of Spanish towns it issued its own emergency paper money during the Civil War after the collapse of small-change supply in 1936–37. These local issues — collectively known as billetes locales or moneda de necesidad — were typically authorized under Republican decree and printed with whatever resources the municipality had on hand, which usually meant rudimentary typography and limited security features.

The Gari Montaner catalog remains the primary reference for Aragonese local issues, and the -C suffix indicates a variant within the Grañén 1 Peseta series — likely a color, signature, or typographic distinction from sibling issues.
