50 Céntimos Bobera

Bovera is a tiny municipality in the comarca of Les Garrigues, Tarragona — population barely in the hundreds even in the 1930s. During the Spanish Civil War, the Republican zone suffered an acute shortage of small-denomination coinage almost immediately after July 1936, prompting hundreds of Catalan municipalities, no matter how small, to issue their own paper emergency currency under authorization from the Generalitat de Catalunya. Turró's catalog documents over a thousand such local issues, and Bovera's is among the more obscure ones.

The very small issuing population means surviving quantities were never large to begin with.
