9/18/324 CE
Portrait of Constantine 1 on a gold coin
"A gold multiple of "Unconquered Constantine" with Sol Invictus, struck in 313 AD. The use of Sol's image stressed Constantine's status as his father's successor, appealed to the educated citizens of Gaul, and was considered less offensive than the traditional pagan pantheon to the Christians."

On September 18, 324 Roman emperor Constantine I defeated emperor Licinius at the Battle of Chrysopolis  (Scutari, Üsküdar), near Chalcedon (Kadıköy) effectively becoming the emperor of the entire Roman Empire.
