1 Peseta La Seu d'Urgell

La Seu d'Urgell is a small Pyrenean town better known internationally as the co-suzerain capital of Andorra than as a currency issuer. In 1937, with the Spanish Civil War disrupting the supply of Republican coinage, the Ajuntament exercised the emergency powers granted to Catalan municipalities under the Generalitat's decree authorizing local paper money — one of hundreds of such issues flooding Catalonia between 1936 and 1939.

Turró catalogues this as #2370, placing it within the enormous documentary record of wartime Catalan municipal notes. These small-denomination issues were purely functional stopgaps, printed locally with limited means, and most circulated hard until the Nationalist takeover rendered them worthless overnight in early 1939.
