This coin has an unlisted workshop, but quite a few examples are known. It also has a spear over shoulder instead of sceptre; but I think this was a result of the engraver not understanding what he was supposed to engrave, versus an official bust type. Still worth noting, though.
I recently made a topic about this type how RIC VI describes the reverse as Jupiter on eagle, while RIC VII says it is Emperor on eagle. I think that it is Jupiter.
