Mark Antony (not an emperor).
ANT. AVG IIIVIR. R. P. C. praetorian galley right.
Eagle between two legionary standards.
Marcus Antonius ('Mark Antony') was born in 83 BC. He was an ally to Julius Caesar and later a rival to Octavius. Following Julius Caesar's assassination, he formed the Second Triumvirate with Octavius and Lepidus. Immortalised in popular culture for his love affair with Cleopatra with whom he jointly committed suicide at Alexandria in 30 BC. These 'Legion' coins were minted most likely at Antony's winter headquarters in Patrae (Greece) to pay his legions and fleet. The name of the legion is on the reverse of the coin. Unfortunately in this example, the coin is too worn to establish which legion it was issued to.
