From Augustus (27 B.C. - 14 A.D.) to Tacitus (275 - 276 A.D.), the Roman Empire allowed many provinces and cities to mint coins for local use - those coins are referred to as Roman provincial coins (or Greek imperial coins). Most Roman provincial coins were copper, bronze or brass, but silver provincial coins were also issued. There are three subcategories: colonial (mostly Latin legends), Greek imperial (Greek legends), and quasi-autonomous (issued under Roman authority but without the Emperor's portrait). Roman provincial coins are known from about 600 cities, though after Caligula (37 - 41 A.D.) only cities from Greece eastward issued them.
