Tetradrachm - Antiochus VII Antioch

Antiochus VII Sidetes was the last Seleucid king to exercise genuine control over the eastern empire, including a brief but remarkable reconquest of Babylonia and Media from the Parthians beginning around 130 BC. His campaign initially succeeded where his predecessors had failed for decades — until a catastrophic defeat at the hands of Phraates II in 129 BC killed him in the field, effectively ending Seleucid power east of the Euphrates for good.

The Antioch mint was the empire's most prolific under his reign, producing the bulk of the coinage that funded those eastern campaigns.
