25 Céntimos Chert

Chert — today spelled Xert — is a small municipality in the Baix Maestrat comarca of Castellón, and like hundreds of Spanish villages during 1936–1938, its local cooperative issued its own fractional paper currency after the Republic's small-change crisis made metal coins virtually unavailable. The Cooperativa Municipal de Consumo served as the issuing body largely because municipal governments in Republican-held territory often routed emergency currency through cooperatives or consumer collectives to sidestep the legal awkwardness of a town hall printing its own money.

The thick card stock was deliberate — small-denomination local notes in this format suffered brutal handling, and thinner paper rarely survived even weeks of pocket circulation.
