Constantius II - GLORIA ROMANORVM for ID

[Joshmaggosh]

Hi all,
I recently purchased this Constantius II - GLORIA ROMANORVM. I don't have the relevant volume of RIC and my usual method of attributing through finding other examples is giving mixed returns.

I've found examples listed as RIC VIII 196, 199, 205 and others. I understand the RIC volume may be a bit wishy washy, trying to separate these between before Nepotian's revolt, during and after without much of a difference. So... with that in mind, that there may be a mixed attribution, what is an accurate attribution for this coin? Thank you!

Rosette diadem, A in obverse left.
RP mint mark, star in upper reverse right reverse.
26x23mm
4.4 grams.

When assigning RIC numbers to these, it is a bit arbitrary since the biggest difference between the issues is size, and there is overlap, i.e. Second series first group (Magnentius) RIC 195- 197 dia. 25- 26mm, second group (Nepotian) RIC 198- 200 dia. 23- 25mm, third group (Magnentius) RIC 204- 205 dia. 22- 24mm. There is likely no actual way to tell these coins apart.

I have had several pearl-diademed examples that were too small for the first group so I listed them like this-- RIC VIII Rome 198/ 204
