Constantine 1st or 2nd 3.2 gram bronze need a little help

Coin Finder

Any additional info would be great. I know it’s Roman Empire and early 3rd century. I can’t find this reverse though..

Not the end all expert but the bust looks to be of the papa, and the Soli on reverse a pagan image consistent with that. So Constantine I, or the Great.
