Well done, catching this
rarity & giving us a nice writeup to share what makes it special! Interesting to consider how the coin might serve as evidence for understanding just a
bit more about the transition of power from
Titus to
Domitian, and the relationships between Emperor, Senate, and
military in the late 1st Cent.
We gloss all the titles (and titles and titles...) with "
Caesar," "
Augustus," or just "Emperor." (Perfectly reasonable to do so, of course.) But this
type is a great reminder that all those titles and roles are actually contingent processes (at least their timing is), rather than automatic. I assume it was a more-or-less foregone conclusion that the Senate would award
Domitian with those titles, but reading your
gallery explanation, I realize I don't actually know most of their specific purposes -- what powers or sense of legitimacy each of them afforded -- or the consequences of delaying or leaving them unassigned.
This is the kind of coin & commentary that I love to see in the Galleries!
