0.10 Pesetas Boltaña

Boltaña is a small municipality in the Aragonese Pyrenees, and like hundreds of Spanish towns it issued its own fractional emergency notes — vales or cartones — during the 1936–39 Civil War when Republican Spain suffered an acute shortage of small coinage. Silver and copper had been hoarded or melted almost immediately after the conflict began, and the central government's response was too slow and too uneven to reach every village in the Huesca province.

These hyper-local issues were produced by whatever means the municipality had available — frequently a local printer, rubber stamp, or even typewriter — and their legal standing was entirely informal. Redemption after the Nationalist victory was not guaranteed.
