I normally wouldn't be too keen on picking up a pair like this, especially in a lower grade, but both were unattributed, and it's always a good exercise to see if you can nail down what precisely they are from scratch.
The first intrigued me more, as I wasn't recognizing the observe legend right off, and felt like it would probably turn out to be a more obscure emperor.


I'm going with this being an issue of Volusian, and since the portrait is radiate, I'm taking it to be an antoninianus. The problem is it ought then to be silver which it clearly isn't. Perhaps the weak rationale may be employed that it was originally
silvered. In any case, the design seems to conform to RIC 168.
The other seems to be a bit more straightforward.


I have this one as Licinius II, RIC VII 29, Antioch mint.
