5 Pesetas Osso de Cinca

Osso de Cinca is a tiny municipality in the Huesca province of Aragon, and like hundreds of similarly small Republican-controlled towns during the Spanish Civil War, it issued its own emergency fractional currency when metallic coin effectively vanished from circulation after 1936. These locally-issued notes — collectively called "billetes locales" or simply "guerra civil locales" — were produced by municipal councils, cooperatives, and trade unions across the Republican zone, often on whatever paper and printing equipment was locally available.

The Gari catalogue remains the principal reference for Aragonese emergency issues, and the D suffix on this listing typically denotes a specific design variant within the series for this locality.
