1 Peseta Sonseca con Casalgordo

Sonseca con Casalgordo is a municipality in the Province of Toledo, and this note is one of thousands of locally-issued emergency fractional pieces that flooded Spain during the Civil War after the Republic's central government failed to maintain an adequate supply of small-denomination coinage. Municipal councils, cooperatives, and even individual businesses filled the gap with their own paper, most of it printed under improvised conditions with no meaningful redemption guarantee behind it.

The Gari Mon catalogue — the standard reference for Spanish Civil War local issues — assigns this a specific variant suffix, suggesting multiple emission types exist for this municipality. Survival rates for Sonseca issues are generally poor; small-town notes circulated hard and were rarely preserved.
