Coin of Philip II of Macedon

Among my small collection of ancient coins is a bronze coin from the reign of Philip II (359-336 BC) of Macedon, showing on the obverse Apollo's head facing right, and on the reverse a youth on horseback facing right with the name ΦIΛIΠΠOY above. The coin commemorates Philip II's Olympic victory in horse racing (356 BC). Here is an image showing the type, although my coin isn't identical:

The coin was a gift from my son.
