Hi Dalia --
I have had very limited success identifying your coins. The way it's done is to read the inscriptions, or part of the inscriptions, and use them for a database search. The problem is, I can't read the inscriptions from your photographs.
The eagle standing and holding a wreath in its beak is from Alexandria Egypt. The tetradrachm in my picture is from Philip I, 244-249AD. It sold for $38 US dollars during a recent auction. Your coin is very close to my picture and is probably worth that much.
