Front side Augustus
Augustus was the first emperor of the Roman Empire, who ruled from 27 BC until his death in 14 AD. The young Octavius was adopted by his uncle, Great Julius Caesar, and came into his inheritance after Caesar's assassination in 44 BC.
Augustus legacy was the peace and prosperity the Empire enjoyed for the next two centuries under the system he initiated. Every emperor of Rome adopted his name, Caesar Augustus, which gradually lost its character as a name and eventually became a title. In many languages, Caesar became the word for Emperor, as in the German Kaiser and in the Bulgarian and subsequently Russian Tsar. The name of the month "August" in English and most other European languages comes from him.
Back side Roman Forum,
Pax Romana, Romulus and Remus
The Roman Forum is an area of the city of Rome which the ancient city developed around. It is the place where commerce, business, prostitution, cult, and the administration of justice took place. Romulus and Remus were the legendary founders of Rome.
In Roman mythology they were twin brothers, children of Rhea Silvia and the god Mars. Romulus and Remus were found by a wolf who suckled them. The brothers were later found by a farmer who raised them. Pax Romana was the time when there was peace in the Roman Empire. So, »Pax Romana« means "Roman peace". The Pax Romana lasted from 27 BC until 180 AD. It started when Augustus Caesar was the emperor (ruler) of the Roman Empire.
Proverb Iustitia Omnibus translates as “Justice for All”, since Augustus was such a just ruler. He is also known for saying at his deathbad: "I found Rome of clay, I leave it to you of marble".
