The edge is too perpendicular. Most edges are rounded. Look at your genuine denarii to see how edges tend to look. These are atypical.
The edges do indeed look sharper than typical and the thickness is pretty uniform. Also I'm not sure what the indentation along edge with the green discoloration is from. However if it is a fake it's not an obvious one (at least to me ). Nor is it obviously authentic unfortunately though that's the way I'm leaning. If this were my coin I would have posted it to the site just like you did. Sorry I can't be of more help. If you really like it and would like to keep it you could always send it to David Sear for authentication for I think about $45. If he thinks it's a fake you'd have an open and shut paypal case and would only be out the $45. If he thinks it's real you would have peace of mind.
Hmm, I see, the catch is i paid $45 for it, so doesn't make sense to be $90 out of pocket expense. I will stay put, to see what others say, if most people say Nay- i will return it..thank you for your help, Curtisimo
Yeah, that is the problem. Certification can cost more than the coin is worth, so many coins are not sent for this kind of service. Like I said, if you have any doubts, return it. You'll always have that nagging at the back of your mind.
In that case the safest bet would probably be to return it. I just did a quick search over at Vcoins and you can find some really solid examples for that price range. Vcoins is a great place to buy with confidence.
I don't think I quite follow you here. If the coin is concave on one side, wouldn't it be convex on the other? Or do you mean something like a double concave lens?
Just like the others have said...if you're not happy with your coin now you'll never be happy with it. Send it back, ask for a refund.
I was only talking about reverses. Yes, the obverse often bows out very slightly. It is a bad sign when a reverse does it.
Ok, that makes sense. I have seen that and considered it a good sign due to the nature of ancient minting techniques.
