Eusko
The idea of the eusko starts when the AMBES (from French "Association pour la création d’une Monnaie locale Basque, Ecologique et Solidaire") took the example of another currency that was running in France, and thought that could be profitable and applicable to the Basque country.
The choice of the name came up when the AMBES asked citizens to choose a name for their optimal currency.
