10 Centimos Cervera; Casa del Poble

During the Spanish Civil War, the Republican zone experienced an acute shortage of fractional coinage almost immediately after July 1936 — silver and copper vanished from circulation through hoarding, and the central government was in no position to resupply remote Catalan municipalities. Cervera's Casa del Poble, the local workers' and socialist cultural center, stepped into that vacuum by issuing its own emergency scrip. These hyper-local vales were legal within their issuing community and essentially worthless fifty kilometers away.

The perfectly square format is unusual even within the crowded field of Spanish Civil War emergency notes, where odd dimensions were common but rarely this extreme.
