Roman provincial currency was coinage minted within the Roman Empire by local civic rather than imperial authorities. These coins were often continuations of the original currencies that existed prior to the arrival of the Romans. Because so many of them were minted in the Greek areas of the empire, they were usually referred to until fairly recently as Greek Imperial coinage.
Tens of thousands of unique types are known, covering most of the Emperors and Empresses until the late 4th century AD, when the Provincial coinage was discontinued. With numerous huge and impressive examples, as well as unique and interesting reverse types, this coinage remains very popular with the collectors.
