Your images are still out of focus, however I think there is enough
there upon which to make comment.
Based solely on the images, I can see nothing wrong with it. You
are always best advised to have anything like this examined "in
" by a relevant expert in ancient numismatics (specifically!).
The weight is about right, and both of the dies are certainly known
(perhaps more importantly, known to have been struck together).
Your piece is a little more interesting for me, as it does not have a
clear name that is readily readable nor fully discernable (much the
same as several others known from this reverse die).
Those dots and lines are definitely meant to indicate a magistrate's
name, but what that name may be has yet to be determined. Your
piece adds nothing to that equation, unfortunately.
It appears to be a genuine 2nd century BC Silver Drachma from the
city of Ephesus in Ionia.
(and one I'd like to own - hint, hint!)
