0.50 Pesetas Calders

Calders is a small municipality in the Bages comarca of Catalonia, and like hundreds of similarly small towns it issued its own emergency fractional currency during the Spanish Civil War after the Republic's central supply of small coins collapsed almost entirely in 1936–37. The Generalitat de Catalunya authorized local councils to fill the gap, producing a flood of paper fraccions — most printed by regional commercial printers with whatever type and stock was at hand.

Imprenta Boixeda in nearby Manresa handled several of these municipal commissions. The Turró catalog remains the definitive reference for this material, and 590 is a relatively obscure entry even within that specialized field.
