Corinth AR Stater, c. 415-345 BC

Corinthia, Corinth . AR Stater (22–23 mm, 8.36 g), c. 415–345 BC.
Obv. Pegasos flying right, koppa below.
Rev. Helmeted head of Athena to right, behind, two owls; above, EYΘ (retrograde).

Good very fine.

The reverse symbol refers to the owls on 5th-4th centuries Attic dioboloi. Similar reminiscence may be found, for example, on staters Ravel 1029 (Sikyon).
