1 Peseta Barcelona; Unió de Cooperadors

Unió de Cooperadors de Barcelona was a workers' cooperative federation, and this note belongs to the wave of emergency fractional currency — moneda de necessitat — that flooded Catalonia in the summer of 1936 after the military uprising triggered a near-total collapse of small-denomination coinage in circulation. Republican-aligned municipalities, cooperatives, trade unions, and commercial associations all issued their own scrip, some with legal backing, most without.

Imprenta Martí, Marí y Cia. handled a notable volume of this local emergency printing in Barcelona. The cooperative context matters: Unió de Cooperadors operated retail outlets across the city, and their scrip likely circulated primarily among members and in cooperative shops rather than as general-purpose currency.
