10 Céntimos Castellet de Llobregat

Castellet de Llobregat is a small municipality in the Penedès foothills, and like hundreds of Catalan and Aragonese towns during the Civil War, its ajuntament issued fractional emergency paper when Republican-controlled mints could not supply enough small-denomination coinage. The Turró series documents over a thousand such local emissions from 1936–1938, most produced in tiny print runs by local printers with no specialised security printing equipment whatsoever.

Turró#721 is among the more obscure entries — the municipality's population at the time was negligible, and surviving examples are correspondingly rare simply because so few were ever printed.
