CONSTANTINOPOLIS, formerly Byzantium, the most celebrated city of Thrace, derives its name from Constantine the Great, by whom it was enlarged with new buildings, and rendered almost equal to Old Rome; in order that Constantinople should be the capital of the empire in the east, as Rome was in the west.  It was taken by the Turks in the year 1453, by whom it is now called Stambul, and in whose possession it still remains a great metropolitan and royal city.  The coins which make mention of it, were struck either by Constantine or by his sons.

CONSTANTINOPOLIS - This legend appears on the obverse of several brass medallions, accompanied by the helmeted bust of the city of Constantinople, personified; the hasta pura on her shoulders: on the reverses are the several legends of FEL TEMP. REPARATIO - RESTITVTOR REIP. - VICTORIA AVGVSTI - VICT. AVGG. &c. all allusive to the reparations, restorations, and military successes, claimed to have been achieved for the empire, by Constantine and the princes of his family. - Engraved in Havercamp, Cabinet de Christine, TAB. xl.

Constantinople, in a later age, was one amongst the number of those cities to which the right of coining money was granted.  Hence on so many coins, we read, at the bottom, CON. CONST. &c.
