Silver,
Thank you for the correction; forgery was the word I should have used.
I'll preface by saying I'm no expert, as you may recall from our exchange on an Antinous I posted some time ago.
This is clearly an Alexandrian coin. Since the time of the aforementioned post I've looked at a lot of them, both online and in person. I've studied the fake files on Forvm. This coin just doesn't look right to me. Perhaps it's the cleaning, as you mentioned. Could be the photograph, or the light angle. Just my impression.
The wear doesn't seem normal. The detail looks too "deep" but without the clarity I'd expect from an unworn coin. The surfaces look too uneven. The flan for an Alexandrian coin should slope slightly outward to the reverse, which may be hard to see from the photo but which I don't think is present. The cracks in the flan look more like pits to me, whereas most of those I've seen with little wear, as the OP apparently does, have a sharpness to them. Anyway, those are some of the things I'd question ... again, as an amateur.
