The only thing I can tell you is something to hopefully move you in the right direction.
Two words; Athena and Owl.
I must have seen that somewhere at some point and that came immediately to mind when I looked at your coin.
I hope it proves helpful. Just google athena owl...awe heck, I just went and did it. I wanted you to have all the fun but....
From what I have read I believe that you have a modern reproduction of an Athenian Owl Tetradrachm made from brass. The original coins were made from silver.
Here is a site about the originals

http://rg.ancients.info/owls/replicas.htmlBrass repros are being sold on
ebay, saw a couple of search hits on those.
If I'm wrong I'm sure a resident expert will put me in my place!

(edit) I looked at two of the
ebay auctions and, unfortunately, it's exactly what you have. Take a look;
