Ancient Greek coin or an imitation? [επιλυμένο]

3.81 g, 16-17 mm (not perfectly round). Medal alignment. Looks like copper.

Obverse: head of bearded man looking right.

Reverse: an eagle-like bird looking back. Legend above: ΦΙΛΙΠΠ·Π[ΟΛ?]

Is this an ancient coin or just an imitation? 

(I tried to search the catalog in various ways.)

Hello, Your coin is from Philippopolis in Thrace and was minted under Septimius Severus
