@Justin Lee please be careful about posting links. Another member might be bidding on it and doesn't want the extra interest. There is always the possibility of a lurker bidding on your coin. It is always a gamble bidding on a coin from a seller with 0 feedback.
It is a decent, genuine example with a nice obverse portrait and slender reverse. Whoever won it did OK. I do not consider it appropriate to discuss coins at auction before they close. There are a couple minor variations of this one that I have been seeking longer than many here have collected and I would have bid 10x this price had this been one of them. Would I have won? That depends who else saw it. We always advise you either know the coin or know the seller. The winner probably got the coin cheaper because of the number of people who won't bid on a 0 feedback seller. Congratulations if it was you.
Any reason not to think this coin on offer isn't authentic? Seller is not listed on the fake list, has 129 transactions in last 12 months and only 1 negative about a shirt. Appears to not be any where near expert about ancients, has only 3 on sale, others are modern.
