1 Peseta Urrea de Gaén

Urrea de Gaén is a small municipality in the Teruel province of Aragon, and like hundreds of similar towns during the Spanish Civil War, it issued its own emergency fractional currency when the Republic's central authorities could not supply adequate coinage. These locally printed notes — collectively called "billetes de necesidad" or emergency money — proliferated across the Republican zone from 1936 onward, with each issuing council responsible for its own guarantee and redemption.

Teruel province saw some of the war's most brutal fighting; the Battle of Teruel in the winter of 1937–38 effectively ended local circulation of notes like this one.
