25 Céntimos Ontiñena

Ontiñena is a small agricultural municipality in the Monegros district of Huesca, Aragon — during the Civil War, the Aragonese front ran directly through this territory, and local councils across the region issued their own fractional paper money when the Republican government's small change simply stopped reaching rural areas. These emergency emissions were a practical response to coin hoarding and supply disruption, not an exercise in monetary ambition.

The Gari Monerris catalog remains the authoritative reference for these Spanish Civil War municipal issues, and the 1037-C designation places this firmly within the documented Ontiñena emission rather than one of the many uncatalogued or misattributed pieces from the same region.
