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”.)
