1 Peseta Pétrola

Pétrola is a small municipality in the province of Albacete, Castilla-La Mancha, and like hundreds of other Spanish towns, its local council was forced to produce its own emergency fractional currency during the Civil War after the Republican government's inability to maintain adequate coin supply in circulation. These municipal emergency issues — collectively cataloged under the broader "billetes locales" framework — were typically produced with whatever printing resources were locally available, which often meant crude typography, thin paper stock, and inconsistent ink coverage.

The Gari Mon reference places this within a well-documented but sparsely surviving series. Pétrola's wartime population was small enough that total print runs were likely limited, and survivor rates for these hyper-local issues are low.
