The reverse legend Latin is abbreviated and creatively spelled. In full, it would read Aquila Electa Juste Omnia Vincit, "the chosen eagle vanquishes all by right." This is an "initial motto," or "riddle motto," as the first letters of each word spell out A E I O U. A bit of German cleverness that's been a motto of Holy Roman Emperors since Frederick III. Which fits with the title of the Charles (CAROLVS) of the obverse legend: Romanorum Imperator, or Holy Roman Emperor.
