Paper currency. City Hall of Lleida. Fifty cents. June 1937. Spanish Civil War.

During the Spanish Civil War (1936-1939), paper currency played an important role in the economy of both the Republican and Nationalist sides. On both sides, governments and municipalities issued bills that were used as a form of currency to finance the war and facilitate the exchange of goods and services, although with a significant difference in terms of stability and value. The majority of the paper currency issued by municipalities was in the Republican zone.
