I don't know for sure, but I have my doubts. Here is one that fooled me. I sent it to David Sear who confirmed it to be fake:
You're helping others by posting here and supporting the hobby, Ro! Collecting ancient coins is educational, broadens our outlook on the world and it's history, and teaches us to appreciate diversity and tolerance by studying the accomplishments and mistakes of the ancient civilizations.
It’s not that people don’t want to help... it’s just that if we can’t be certain one way or the other, people don’t comment. I think you should send it to someone who can examine it in hand.
I'm not an expert, but I'm skeptical. I think it's not authentic. The nearly perfect centering and the uniformity of the surface texture gives me the impression that it could be a clay casting. The edges are displaying the same fine pebbling of texture. When I look at my bronze coins I usually see a variety of smoothness and roughness.
The wear pattern on the obverse seems a little weird to me- almost all the legend is very clear, except at the bottom between 4 and 6 o'clock where it is suddenly heavily worn, even though all the legend is well within the flan. If you are feeling uncertain about this coin, it may be worth getting it examined by David Sear or NGC. Also, I think you may be having unrealistic expectations for how quickly you will get reactions to your message. It is only 2 hours since your original post, and taking into account a) multiple timezones of CoinTalk members, b) not everyone is online all the time, c) not everyone feels comfortable posting their opinion until they see what other trusted members are saying, it can take a while before you will get feedback. I just got back from a week-long vacation, and am catching up on CoinTalk in between unpacking, updating my eBird records, making dinner, and other tasks, and I expect other members are just as busy. I would suggest you wait at least a full day before you get worried about lack of replies to your post.
I am sorry to say I doubt it's authenticity for a couple reasons: 1 The wear on the reverse seems much different than the obverse B The fact that you are concerned makes me think the seller is not one to be trusted Ps, from one ro to another, chillax. Some of us have day jobs and families. I post questions a plenty and it can take time to get a response. Patience
