1 Peseta Castillo de Locubín

Castillo de Locubín is a small municipality in Jaén province, Andalusia, and like hundreds of Spanish towns during the Civil War, its municipal council issued emergency fractional currency when Republican-zone coinage vanished from circulation almost overnight in 1936–37. These local emissions — collectively known as "moneda de necesidad" — were produced under no central oversight, which is why surviving examples vary so dramatically in paper quality, print registration, and even denomination values from run to run.

Provenance for individual pieces is nearly impossible to establish. Few left the town at all.
