5 Centimos Barcelona; Ferrocarril Metropolitano Transversal

Barcelona's metro network issued its own emergency small-change tokens during the Civil War years when metallic coin virtually vanished from circulation. The Ferrocarril Metropolitano de Barcelona — specifically the Transversal line, which had only opened in 1933 — produced these transit scrip notes to cover fares and change when the Republican-controlled city economy was fragmenting under wartime pressure. Hundreds of municipalities, businesses, and transport entities across Catalonia did the same under the auspices of the Generalitat's emergency currency decrees.

The AL reference places this within Andreu i Llopis's catalog of Catalan civil war necessity issues, a classification distinct from the better-known CCMA series.
