Old coin

I bought this coin off catawiki, but I don't see it on this website. I was hoping for help.

Obv: Bust of Artemis right, bow and quiver over shoulder
Rev: [EΠI] ΔHMHTPIOΣ KΩ-KOΣ ΣΩΠATPOΣ, two stags standing facing each other, Ε-Φ below, torch between.

Hello, I think this from Stymphalos - (Ancient Greece) 

I can't find your coin on Numista.
