15 Céntimos Lloá

Lloá is a tiny village in Baix Camp, Tarragona — the kind of settlement whose wartime municipal council had no business issuing currency, yet did exactly that under the anarchic monetary conditions of Republican Catalonia in 1937. Hundreds of Catalan and Aragonese municipalities printed emergency fractional notes during this period, most through whatever local printer was still operating. Josep Bassa in Mora d'Ebre served several such councils along the Ebro valley.

The official stamp is the only security feature — which tells you everything about the trust model these notes relied on: purely local, purely social.
