The Fleet coinage was a set of bronze coins minted by Mark Antony in the eastern Mediterranean from 40 BC until 30 BC. The coinage introduced Roman-style denominations to the eastern half of the Roman empire and formed the basis for the monetary reforms under Augustus. The coinage is also referred to by numismatists as RPC 1 1453-70 and 4092, after their designation in M. H. Crawford, Roman Republican Coinage (1975).
