This Greek coin is a silver Tetradrachm from Macedonia in northern Greece. It was struck in the late 4th century BCE. The obverse shows a profile of Hercules, son of Zeus and symbol of strength, wearing a lion skin. The reverse is a seated Zeus, Greek king of the gods, seated on a throne. In his left hand he holds a scepter and in his right hand is an eagle. To the right of Zeus are the letters ΦΙΛΙΠΠΟΥ (Phi Iota Lambda Iota Pi Pi Omicron Upsilon) denoting the coin as being for Phillip III, known as Aridaeus, king of Macedonia for this time period. Underneath Zeus are the letters
ΑΣΙΛΕΩΣ (Alpha Sigma Iota Lambda Epsilon Omega Sigma) (the B Beta is missing at the beginning), the Greek word for king.
