The style, lettering and surface anomalies suggest to me that this coin is not genuine. I would love to see the edge and know the weight.
Dont get me wrong, its well done and could easily pass for those unfamiliar with the series. They even got the number of strings correct on the lyre (which is where many would mess up), but the style is something forgers usually just cant replicate. Also, genuine examples are almost always right at 14.4 to 14.5 grams. The photos of the edge are blurry but they look odd, like they have been artificially distressed to conceal a casting seam (perhaps).
Yes, your coin is real; however, it is not a genuine piece. That's a statement I've heard one professional coin authenticator use on persons asking for his opinions. IMO, this piece should not fool an ancient coin dealer or collector with any experience. Nevertheless, counterfeits such as this are much nicer (more authentic looking) then the usual crude copies made to sell to tourists. Wish it were in my collection of counterfeits!
Awww, that's too bad ... I always hate hearing about fake coins (funny though, the weight is in the ol' ballpark, eh?)
That is too bad Kristos, where did you get the "coin" from? I hope you can return it and get your money back.
