Kassander King of Macedonia from 305 BC to 297 BC.
Kassander was king of the Kingdom of Macedon from 305 BC until 297 BC, and de facto ruler of much of Greece from 317 BC until his death.

In his youth, Cassander was taught by the philosopher Aristotle at the Lyceum in Macedonia. He was educated alongside Alexander the Great in a group that included Hephaestion, Ptolemy and Lysimachus.

Cassander stood out amongst the Diadochi in his hostility to Alexander's memory. Both Alexander IV, Roxana, and Alexander’s supposed illegitimate son Heracles were executed on Cassander's orders, and a guarantee to Olympias to spare her life was not respected.

He died of dropsy in 297 BC

It seems debatable whether the reverse is supposed to have the spear straight up or on its side with the inscriptions horizontal, I've seen it both ways
