50 Céntimos Castuera

Castuera is a small town in Extremadura, and like hundreds of Spanish municipalities during the Civil War, its local council issued its own fractional paper currency when coin shortages made everyday transactions nearly impossible. These emergency emissions — known as papel moneda local — were produced under no central authority, often printed on whatever stock was available, and backed by nothing more than municipal goodwill.

The Gari Mon reference places this within a documented but sparsely catalogued series. Many Extremaduran municipal notes were produced in tiny quantities and saw only weeks of use before the front shifted.
