Might've mistaken with Basque country in particular and France in general—guess I majorly botched all those vague recollections in the comment.
Wikipedia lists four local currencies in France: Abeille, Eusko, Krôkô, Occitan (https://en.wikipedia.org/wiki/Local_currency). And also says, “The eusko is one of a number of currencies that are active in the Basque Country”.
Fell in to this rabbit hole a little earlier, so I'll try to drag you in as well. If you switch languages on Wikipedia the list grows a whole lot¹.
FWIW, I've only ever seen one local note in the UK and that was on somebody's fridge ~100km from Bristol where it would actually be valid. I suspect there is a fair amount of money trapped in scrapbooks and on fridges ;)
Good idea, I've perused the Spanish page on ‘local currencies’ and count seven of them (https://es.wikipedia.org/wiki/Moneda_local)—though on the English WP the topic is split across several articles. I'm also guessing the list might easily be incomplete.
(Also the ‘eQ’ thing on this page sounds like someone's marketing campaign, so perhaps should be cleaned up or removed. E.g.: “aims to promote local consumption, increase the purchasing power of people (for €1 you get 1.50eQ)”—wow very smart, much increase; but later suddenly “€1 = 1eQ”.)
