Im traveled in Slovenia (in real not of course) and bringing back two souvenirs and some money that I was lucky enough to take home, all in very perfect and excellent condition.

Banknotes of 100, 50, 20 and 10 tolar (Slovenian thaler) all of 1992 (in fact, the very first issue of such design after the transition model of 1991), coins of 5 tolar and 50 stotins (kopecks, pennies) also of the 90s (I do not have 2000s yet), and on them are depicted important persons and symbols related to their profession or their own noble business, and on the coins of animals, bee, long-horned goat, fish, unusual lizard and others.
This whole affair went from 1991 to 2007, when on 1 January of the latter year it was all quickly replaced by the euro, which has been going around since then there still officially.

Well, and the dragon though was not on money (except for one single case and not in this time), but it was and remains as a coat of arms of the capital of Slovenia Ljubljana, and it is visible on this badge (I do not know what year and who issued it), and also on a familiar to someone postcard of 70 years of the time of Yugoslavia Tito as a statue of the dragon bridge there.
