50 Céntimos Santa Eufemia

Santa Eufemia is a small municipality in the province of Córdoba, and like hundreds of similarly sized Spanish towns, it issued its own fractional emergency currency during the Civil War after coins vanished from circulation almost entirely by mid-1937. The Republican zone's chronic small-change shortage drove municipal councils — bodies with no banking infrastructure and no formal printing arrangements — to produce what they could locally, often on card stock cut to size rather than purpose-manufactured banknote paper.

The Gari Mon cataloguing places this within a well-documented but still incompletely surveyed series of Andalusian municipal issues. Survival rates for these cards are low; many were redeemed and pulped, or simply discarded once the Nationalist advance rendered them worthless.
