Front side Marcus Aurelius
Marcus Aurelius Antoninus Augustus was a Roman Emperor from 161 to his death in 180. He was the last of the "Five Good Emperors", and is also considered one of the most important stoic philosophers. His rule was marked by wars in Asia against a revitalized Parthian Empire, he also fought against Germanic tribes along the Limes Germanicus into Gaul and across the Danube. During the wars against the Marcomanni under his rule several combats took place on the Danube and the Tisza river. That is why coin chosen for this banknote is a silver denarius depicting a warship.
Back side Roman Legion
On the back we see a roman legion which consisted of several cohorts of heavy infantry known as legionaries. It was almost always accompanied by one or more attached units of auxiliaries, who were not Roman citizens and provided cavalry, ranged troops and skirmishers to complement the legion's heavy infantry.
The size of a typical legion varied widely throughout the history of ancient Rome, with complements of 5,500 legionaries in the imperial period of Rome, split into 10 cohorts of 480 men each, with the first cohort at double strength: the remaining 220 being cavalry and technical staff. The coin shows signa militaria, which were the Roman military ensigns or standards (flags).
Fortes fortuna Iuvat - "Fortune favours the brave". The phrase means that Fortuna, the Goddess of luck, is more likely to help those that take risks and take action, than those who don't.
