Who Is This Emporer?

Bing.




I guess ancient engravers also had bad days, maybe this was a hangover coin

It is often quite difficult to determine the emperor from the portrait alone at this peiod. Durnig these times of turmoil the mints needed to carry on minting coins during a regime change. The easiest way for them to do this was to continue to use the portrait and reverse types (and likely reverse dies) from the last running issue of the previous emperor and add new obverse legends. This was intended to be short term whilst they awaited the approved portrait of the new emperor and the new political message to be conveyed through the coinage was decreed. This leads specialists to look for these interesting transitional coins and pick them out.

During the Tetrarchy, the portraits on Folles lose a lot of their individuality and become homogeneous it becomes very difficult to tell emperors apart even within the same issue.

Thank you Ron, the coin didn't arrive yet it has to cross the Northsea.
Martin I think that's exactly what I wanted to say, Lugdunum is your speciality do you have any specimen related to this subject?

This is the first SS I've seen with straight hair.
