...just for the record, below is a close-up of the
bust. As you can see there is something sticking out. I agree that it's not
aegis as it should be...but
still, I believe that it was intended to be an
aegis, but the die cutter did a mistake or something happened to the die. Also, couple of years ago I saw the coin from the same issue with the same
bust with semi-aegis but in much better condition on some other numismatic
forum, probably from the same dies,- unfortunately I cannot retrieve that
thread. That other
denarius was minted much more prominently, so that this 'semi-aegis' was more evident.
