In AD 330, Constantine the Great founded and named the city of Constantinople after himself (humble guy, eh?), thereby establishing it as the first Christian capital of the Roman Empire. Struck in celebration of the city's founding, the obverse of this ancient commemorative coin featured the helmeted goddess Constantinopolis herself. A winged seraph appeared on its reverse, symbolizing protection and victory. Associated with Christianity, the figure would later come to be known as a guardian angel. Circulated quality.
