Ptolemaic period in Egypt?

Hello folks, I got this coin that is believed to be from the Ptolemaic period of Egypt.

The coin is 19mm and 5,27 gr.

It looks like an Egyptian one but the eagle seems to be different.
Maybe someone have seen it before?

There are a lot of different Ptolemaic eagles. This was a long period with more than 12 different rulers and multiple series of coins in some of them.

Here is a site that has helped me a lot: http://ptolemybronze.com/
