Seleukos I Nikator AR Tetradrachm authenticity

[vaxtankava]

Dear Colleagues, with only these photos available is it possible to qualify this coin as not being a fake?
Thanks in advance for your help!

What is the weight? Some details (lettering) appear to be soft.

Unfortunately weight is not available, hopefully will get it by tomorrow…reverse design looks kind of blurred to me as well

The weight is 16.2 g, should be 17.0 if I'm not mistaken

Hot silver occupies a greater volume than cold, so a cast coin, coming from a mold taken on the original, is a bit lighter and has a volume slightly lower than it.

A really tough call. While I cannot condemn it outright, the light weight and muddled lettering would convince me to avoid it. BTW, it purports to be from the Ecbatana mint. My experience with Ecbatana coins of Seleukos I indicates a fairly strict adherence to the weight standard of 17.0 grams minimum.....most with even a slight amount over 17.0 grams....like 17.1, 17.2, and even 17.3 grams.
Your call.

Suspect, but perhaps harshly cleaned - which may explain what I don't like about its appearance. You really need to see it under a scope to determine whether it is struck or not.

Yes, thanks, you were right!! the seller of the coin has just confessed he cleaned it with an acid   something he denied before
