5 Céntimos Torrente de Cinca

Torrente de Cinca is a small municipality in the Aragonese province of Huesca, and this 5 céntimos note belongs to the emergency local paper money — known as moneda local or billetes de necesidad — issued across Republican-held Spain during the Civil War after the hoarding and melting of coins created acute small-change shortages from 1936 onward. Hundreds of municipalities printed their own fractional notes, many with no more authority than a rubber stamp and a council resolution.

The official stamp is the only security feature, which was entirely typical of these issues and did almost nothing to prevent counterfeiting — not that the hyperlocal circulation made forgery much of a commercial proposition.
