This is a stunning Silver Tetradrachm of King Demetrius II Nicator 161 BC - 125 BC. Son of King Demetrius I Soter, he went into exile when his father was killed fighting the usurper Alexander Balas in 150 BC. Demetrius returned to Syria with an army of Cretan mercenaries, deposed Balas, and installed himself on the throne. He drove back a Parthian invasion but was defeated and captured by the Parthians. Demetrius was released from captivity in and returned to Syria, but, during his second reign, he controlled only part of the kingdom. He was assassinated about four years later in 125 BC.
