50 Céntimos Alpera

Alpera is a small municipality in the province of Albacete, Castilla–La Mancha. This 50 céntimos note is one of thousands of emergency paper issues produced by Spanish municipal councils during the Civil War, when the Republic's central government could not adequately supply small-denomination coinage to rural localities. The Consejo Municipal effectively printed its own fractional currency out of necessity — metal had been hoarded, melted, or simply vanished from circulation by 1936–37.

The Gari Montañà catalogue remains the primary reference for these local Spanish issues, many of which survive in tiny quantities because production runs were small and redemption was often chaotic or never completed.
