It took a hard glancing hit from the northwest (if you orient the coin to read normally). Metal was pushed down and to the right, creating the higher portion you mention. It's a pretty common thing, which tends to surprise people because it's hard to imagine a coin taking an impact strong enough to move metal in that one small place. But it happens, and frequently.
Blue Lue Boyle said "Isn't it the general concept of an 'error' to contradict what's seemingly possible?" Well, no, I don't think it is. First of all, I meant no disrespect. Second, if there is no way that an "error" can be explained, it can't be an error. Then it must be post mint damage of some kind. Please correct me if I am wrong about this. Steve
So do the mods restore a post in a case like this here. I hate when people do this childish stuff with their op threads
Not worth getting worked up over. I wouldn't have bothered restoring it; more likely just a lock. Restoring it reeks of vindictiveness.
