15 Céntimos Samper de Calanda

Samper de Calanda was a small agricultural village in Teruel, Aragon, where the CNT-affiliated collective took control of local economic life during the Spanish Civil War. Like dozens of similar village collectives in 1936–37, they issued their own fractional paper to replace coin that had vanished from circulation almost immediately after the July 1936 uprising — hoarded, melted, or simply absent in rural economies that had never seen much of it. These local emissions had no legal standing under any central authority, Republican or otherwise, and were redeemable only within the issuing community.

The CNT collectives of Aragon represent one of the most documented experiments in anarcho-syndicalist economic organization in modern history. Samper de Calanda's scrip circulated for roughly a year before the Lister Division's suppression of the Aragon collectives in August 1937 rendered it worthless overnight.
