50 Céntimos Ontiñena

Ontiñena is a small agricultural municipality in the Monegros district of Huesca province, Aragon. Like hundreds of similarly sized Republican-held towns, its local council issued fractional paper currency in 1937 to address the acute coin shortage that followed the hoarding and melting of metallic currency in the early months of the Civil War. These municipal emergency notes — collectively termed moneda local — were authorized under Republican government decree and had no validity beyond the issuing municipality's boundaries.

Survival rates for Ontiñena issues are low simply because the town's population was small and total print runs were limited accordingly.
