Nice score 7Calbrey, I have a couple from Tincium mint they both just happen to have the Temple of Romulus, still standing in the Forum today. And below another Tincium, Divo Constantius.
RIC VII, 3 has Sol facing left. Coinage of Constantine from before 313 CE is in RIC VI, which can make things confusing if you don't know the cutoff date. I should probably get into the habit of including the volume number with these early Constantines.
