25 Céntimos Mosqueruela

Mosqueruela is a small hilltop municipality in the Gúdar-Javalambre highlands of Teruel, Aragon — remote enough that during the Spanish Civil War, the breakdown of the national monetary system hit hard and fast. Local councils across Republican-held territory were authorized, informally at first and then more systematically, to issue their own emergency paper to keep commerce moving when coinage vanished from circulation entirely, hoarded or melted down. These municipal emissions, known broadly as "guerra civil local issues," were printed or lithographed under improvised conditions, often by whoever had access to a press.

The Gari Montalvo census remains the primary reference for Aragonese municipal issues, and the 977-A designation suggests this is among the documented variants rather than an unrecorded type — though survival rates for Teruel province issues are generally low given the intensity of the 1937–38 fighting in the region.
