The early Greek king of Egypt, Ptolemy I, chose as his insignia Zeus’ eagle perched on a thunderbolt.
It was the principal reverse type of his kingdom’s coinage for 250 years.
Unless you found it in Europe or Egypt, I'd be suspicious of its authenticity.
Hope I'm wrong.

Wow Don thank you so much this is extremely similar to the coin I have! I'm going to weigh it tomorrow hoping it's 13.91g , does it have to way exactly that amount? I would think that it wouldn't being so ancient

In the Ptolemaic empire, Ptolemy I Soter began reducing the weight to 15.8g then 14.9g then 14.3 g.
By the early first century the weight was down to 14.2g.
So, no,your coin need not weigh exactly 13.91g.
You may wish to take it to a jewelry and test it for being silver or pewter.

The coin I featured was placed in a June 27th auction in London (Spink and Son) but did not sell.
The value was estimated by Spink as between @200-250 GBP.
