Hello, I am trying to identify this coin and I am not getting very far. The obverse has a head (nymph ??) right , and the reverse has an Eagle with wings spread angled left but facing right. There appears to be a Thunderbolt in it's claws. While most of the ones I have found similar to this have Delta Theta in the above fields, my coin has Delta Alpha there. AE8.6mm., 5.37gm. Any help is appreciated.
I wondered about Perseus and his 'winged hat', but I convinced myself that what I was seeing was not a wing. Thank you @Ryro .
