10 Centimos Martorell

Martorell issued these cardboard emergency notes — technically "moneda local" rather than coin in any metallurgical sense — during the chaotic monetary collapse of the Spanish Civil War, when the Republican government's inability to supply sufficient small change forced hundreds of Catalan municipalities to print their own. The Generalitat de Catalunya had authorized local issues in 1937, but coordination was loose and quality uneven across issuers.

At 36mm, Martorell's issue runs notably large for a 10-céntimos denomination, likely reflecting cardboard's poor durability — bigger surface area meant the disc held together longer under circulation wear.
