Saw this listed on ebay, no reverse but wow that neck is one of the longer one's I have seen for him & my very first one was a longneck. I read these are usually referred to as "giraffe necks", this qualifies. I find it very unappealing. Makes you wonder if the engraver did it for his dislike of the emperor or what.
Yeah, Wrong! It's clearly an Aurelian and not a Probus as listed. Other than that, I actually quite like it. The meerkat look suits him.
I've always thought is was curious that that long-necked bust varieties occur on the ants of Aurelian and Probus, but not on the coins of the other emperors around that time, Quintillus, Tacitus, Florian, Carus...It's an odd little mystery in the annals of Roman numismatic quirkiness.
Claudius I has a pretty long neck on his Gallic mint bronzes. As a long-necked individual, I think these are perfectly normal coins.
