50 Céntimos Ribarroja

Ribarroja — now Riba-roja de Túria, a small municipality in the Valencia region — issued emergency fractional currency in 1937 under the authority of its municipal council, as did hundreds of Valencian and Catalan townships during the Spanish Civil War. The collapse of small-denomination coinage in Republican-held territory forced local bodies to print their own substitutes, a phenomenon so widespread that Turó's catalog of Valencian paper money alone runs to thousands of entries.

The dual reference — Gari Monetario and Turó's provincial catalog — reflects the overlapping documentation efforts that emerged decades later to bring order to this chaotic emission. Many Ribarroja pieces were printed in tiny quantities and saw only hyper-local use before the Nationalist advance into Valencia in 1939 ended their validity.
