50 Céntimos Lliber, Federico Reus

Lliber is a village in the Marina Alta comarca of Alicante, with a population that barely exceeded a few hundred during the Republic. Like dozens of similarly small Valencian municipalities, it issued its own emergency fractional currency in 1937 when the Nationalist blockade and the Republican government's inability to distribute small coinage created a near-total shortage of change. These local wartime issues — collectively catalogued under the Spanish Civil War municipal series — were legal only within the issuing town's boundaries.

The printer, Imprenta La Gráfica of Elche, handled a number of these emergency issues from the surrounding region. Federico Reus, named on the note, almost certainly served as the municipal authority who signed or authorized the emission rather than as a printer or designer.
