If it is an AE12, three possibilities, depending on what's in front of the stag:
Magistrate Peristratos. 350-340 BC. E-Φ to left and right of bee / ΠΕΡΙΣΤΡΑΤΟΣ, stag recumbent left, head right, astragalos above. Pixodarus note 32, 11.
Magistrate Boiotos. E-Φ to left and right of bee / ΒΟΙΩΤΟΣ, Stag recumbent left, head right, astragalos above. Berlin, Pixodarus note 34, 3.
Magistrate Ekatokles, 305-295 BC. E-Φ, bee / EKATOKΛHΣ, stag recumbent left, head right, astragalos to right. SNG Cop 248; Head Chronology, p. 38, class c, 4.
I think I see some remnants of ΠΕΡΙΣΤΡΑΤΟΣ (bottom of letters to left)
