Thank you for your comments. Yes I agree, it is most likely
Elagabalus. Maybe they wanted him to look a
bit like
Caracalla who was fairly popular in the army, or maybe he actually
had a short beard that morning on May 16, 218 when the legion in Raphanea pronounced him emperor of the empire.
It would be great to learn more about the
symbols on the
reverse, any comments are very welcome. Jochen, thank you for the links. I will study them to learn a
bit more.
Best regards, Jan
