Please help identify old coin

Want to share my new acquisition, old silver coin maybe roman between 300-400AD.
Thanks in advance.
Abdel,

 

Writing on the back is Greek.

 

Tetradrachm of Ptolemy III uses similar images:

 

I can find many Ptolemaic coins with an eagle on the reverse that is similar to the one on the tetradrachm above, but the bird on the reverse of yours looks more like the goddess Nekhbet:




However, I'm not turning up any coins searching for either Nekhbet or vulture.

The upper word I think is 'BASILEOS', King.

 

I would look at Antioch & the Seleucids too.

Are there any letters here, or only tail feathers?

 

Nothing is written there

 

A word of caution: There are lots of fakes/replicas out there. Some are sold as inexpensive souvenirs around tourist sites while others are quite deceptive to even experienced coin collectors.

 

I don't know about Abdel, but I have not been assuming at all that this a genuine coin or even a copy of a genuine coin.

The reverse looks related to this one for King Perseus:

The figure on the obverse of OP's coin is clearly someone else.

 

It is an artist's rendition of an old coin made for modern jewelry
