50 Céntimos Fayón

Fayón is a small municipality on the Ebro in what was then the Aragonese front — one of the most contested stretches of the Civil War. Like hundreds of Catalan and Aragonese councils in 1937, the Consejo Municipal stepped in to fill a vacuum left by the near-total disappearance of metallic coinage, hoarded or simply gone. These hyper-local emergency issues were authorised under Republican decree but produced entirely on local means, which is why paper quality, printing registration, and ink consistency vary so dramatically even within a single denomination.

Gari Mon#636-B distinguishes a specific variant — likely a colour, paper, or typographic difference from 636-A. Fayón's issues are among the scarcer Aragonese municipals; the town's population was tiny, production runs were small, and survival rates suffered accordingly.
