In Spain, since 1988, in the Axarquía region of Málaga province, a privately initiated "unofficial" monetary system called Axarco was created. Its coins and banknotes circulated throughout the region as a means of payment in shops. Equivalencies were established with the Spanish peseta, and the creator of the fictitious currency had previously made a deposit in a bank branch equal to the amount of banknotes and coins put into circulation.
Isn't it appropriate to add “1 Axarco = 100 Pesetas” (at the least that' the exchange in Wikipedia) and its value in euro as well? I know peseta and euro aren't subunits of axarco, but there is an equivalency.
This monetary system may have had limited use as a local currency alongside the peseta, but certainly not with the euro. Nor has it been reissued since 1989. So I wouldn't say it's a 1988-date local coin, but rather a 1988-1989 one.
By the way, the x in Axarquía or axarco is pronounced j in Spanish, like in México or Texas.

Taking into account what you've said @mrcsp and @zegeri I think it's best to classify coins and banknotes as local (I'll do it now) and the monetary system would look like this:
The monetary system to be added is:
Axarco (1988-1989)
1 Axarco = 10 Axarquillos = 100 Pesetas
The existing denominations, for both banknotes and coins, are:
