A couple of months back I bought this lovely Antiochus coin on eBay: I'm happy about this purchase but a few weeks ago I learned about the NFSL on CoinTalk (thank you @TIF). From that point on I started investigating some of my previous purchases on eBay... this is one of them, and yes, it was bought from a seller that is listed on the NFSL (this guy has very positive feedback from thousands of users) Until now I had no doubt about the authenticity of this coin... So once again, I'm asking for your wisdom and thoughts on this. A few more pictures from other angles: Cheers
I can make a good guess which seller you are talking about. They have more fakes than authentic coins, but yours looks fine. I occasionally look at their Seleucids to see if anything interesting shows up. One of mine from a different seller.
I have two Antiochos IX Tetradrachm Antioch mint 16.71 grms SC 2363a (this coin illustrated) HGC 1228i (this coin illustrated) And this one Antiochos IX Tetradrachm Antioch Mint 16.14 grms SC 2369/3
Based on the photo, (and not on the seller), I see no reason to doubt the authenticity of the OP. Enjoy.
