The coin is probably OK, but it really is impossible to authenticate a coin like that from a photo. Some
cast denarii are very difficult to detect in hand and impossible to detect in photograph.
By the way, we do not discuss coins here is coins we are pretty sure are genuine. Imagine if everyone posted all the coins they think are genuine but just are not sure. There would be so many posts that we would never discuss the more interesting actually suspected coins. Only post coins you think are probably
fake here, not coins you think are probably genuine. That is one of our many rules.
Also, if you have to ask about a coin you just bought, you should not have purchased it. Before you buy a coin, either: 1) know the coin is genuine, or 2) know the seller has expertise and a guarantee. In short, know the coin or know the dealer.
