25 Céntimos Estada

Estada is a tiny municipality in the Somontano de Barbastro comarca of Huaesca, Aragon — the kind of village that would never appear in a banknote catalog under any normal circumstances. It issued emergency paper money in 1937 because the Spanish Civil War had effectively destroyed the small-change supply across Republican-held territory. Hundreds of Spanish municipalities did the same, producing what collectors call "billetes de necesidad."

The Gari Montane corpus documents these Aragonese local issues exhaustively, and Estada's entries are among the scarcer provincial pieces — the issuing population was simply too small to have produced large quantities.
