10 Céntimos Torrente de Cinca

Torrente de Cinca is a small municipality in Huesca, Aragon, and like hundreds of Spanish localities during the Civil War, it issued its own fractional emergency currency when the republic's small-change supply collapsed after 1936. These local council emissions — called *billetes de necesidad* — were authorized under republican decree but produced entirely at the local level, which accounts for the extraordinary variation in quality, material, and format across the series.

The square format here is a direct consequence of paper scarcity rather than any design decision.
