About the ex-jewelry notation

The NGC label indicates that the coin was formerly mounted or otherwise used as jewelry. Prior mounting may leave evidence along the edge or surfaces and can affect collector value.

The notation does not establish the form of jewelry, the mounting method or when the coin was mounted. No representation is made that it was used as jewelry in antiquity.

Historical note

Constantine I, commonly called Constantine the Great, emerged from the political struggles of the Tetrarchic period and became sole ruler of the Roman Empire in AD 324. His reign transformed the imperial government, established Constantinople as a new center of power and marked a decisive shift toward imperial support for Christianity.

Camp-gate designs appeared extensively on fourth-century Roman bronze coinage. Their fortified architecture and accompanying imagery communicated themes of imperial protection, stability and preparedness across the empire.
