If you want folks to comment as to authenticity, then you should probably post cropped photos that depict the details of the coin's obverse, reverse, & edge. Also, folks would want to know the accurate weight and dimensions of the piece. Also weather the piece is magnetic & from where you got it. P.S. (The gorgon design from the black sea area is a highly faked design).
Usually it is best to have one coin per post but these all sharing the same reverse suggesting they are a set together could have been posted together. That would have made it easier to post that all are fakes.
