20 Centimos Belvis de la Jara

The origin of this cardboard currency must be sought in a decree of the Council of Ministers dated February 24, 1938, by which the issuance of cardboard discs, printed on one side only, was authorized. with the coat of arms of the Second Republic, to which a postage stamp was affixed on the obverse, which was what established their monetary value - normally reduced, just a few cents - of them.

However, there are some items on the market that did not include the aforementioned shield of the Second Republic, but rather various motifs along with the names of different Spanish towns that, presumably, would have issued them... All of them dated in 1937 - that is, prior to the aforementioned decree of 1938.
