50 Céntimos Susqueda

Susqueda was a small municipality in the Garrotxa comarca of Girona province, and like hundreds of Catalan and Spanish towns during the Civil War, it issued its own fractional paper currency when metallic coin disappeared from circulation almost entirely after 1936. These hyper-local emergency notes — often called "moneda local" or "bitllets de necessitat" — were authorised under Republican decree and produced in enormous variety, with quality ranging from professional lithography to hand-stamped cardboard. Susqueda's falls toward the modest end of that spectrum.

The town itself no longer exists. It was submerged in 1962 when the Susqueda reservoir was completed, displacing the entire population. Notes from the municipality are consequently among the more sought-after Civil War locals — not for rarity alone, but because the issuing authority was literally erased from the map.
