5 Céntimos Castellar del Vallès

Castellar del Vallès, a small industrial town north of Sabadell, issued cardboard emergency currency in 1937 as the Spanish Civil War severed normal coin supply chains and the Republic struggled to maintain a functioning monetary system at the municipal level. Hundreds of Catalan municipalities did the same, producing what collectors now catalog as moneda local — locally sanctioned scrip that filled the vacuum left by hoarded metal coinage.

Cardboard issues survive in wildly varying condition depending on wartime handling. The Turró and Gari Mon references remain the two authoritative catalogs for this material.
