50 Céntimos Alcubierre

Alcubierre is a small municipality in the Monegros desert region of Aragón, and during the Spanish Civil War it sat directly on one of the most static front lines of the entire conflict — held by anarchist and POUM militias for years. Local cooperatives in Republican-controlled towns frequently issued their own emergency paper when coin vanished from circulation, hoarded or melted, and the central government's supply chains offered no reliable substitute.

The Gari Mon reference places this among the documented Aragonese local issues, a category that saw hundreds of distinct emissions from villages that would otherwise leave almost no monetary record. Many were printed on whatever paper was at hand and redeemed — or simply abandoned — when the front collapsed in 1938.
