50 Céntimos Rubielos de Mora

Rubielos de Mora is a small hilltop town in Teruel province, and in 1937 it was deep within the Republican zone as the Aragonese front ground on. Like hundreds of other Spanish municipalities that year, the local council issued emergency fractional notes to plug the near-total disappearance of metallic coinage — silver and copper hoarded or melted almost immediately after July 1936. These town-issued pieces, known collectively as "billetes locales" or "papel moneda municipal," were legally tolerated by the Republican government as a stopgap but never formally sanctioned at the national level.

Survival rates for Teruel municipal issues are uneven; the town changed hands violently during the Battle of Teruel in late 1937 into 1938, and much locally-held paper was lost or destroyed in that fighting.
