While I do not wish to question the judgement of people with way more knowledge than I have , ( although I shall!
), are you entirely sure that this is official, or perhaps could be a
very good imitation ?
The
style of the
portrait very much reminds me of imitations I have in my own
collection, the jawline and beard just do not look particularly flattering... Certainly not a befitting of an emperor ..
Check out the first few coins in my ( admitedly small )
collection of imitations for some VERY similar obverses..
