Good job at narrowing it down @furryfrog02 ! Sometimes these Constantius, Constantinus, and Constans types are tough to identify. One thing I have noticed is that the head of Constantius II is usually depicted as narrower than Constantinus II in the portraiture, whereas Constantinus II is a bit more beefy. If that weren't enough, family member Delmatius also struck GLORIA EXERCITVS types. There was yet another family member who also struck coins, the short-lived Hannibalianus, but his coins depict the reclining Euphrates, rather than the GLORIA EXERCITVS type.
