The first coin I could post after IPad photography belongs to Antoninus Pius. It weighs 10.9 g. Still I can't read reverse in a clear way.
That is infinitely better than your "high resolution scans" which aren't in any way high resolution or adequate for showing a coin! Here are your images after cropping, joining, and attempting to white balance (a failed attempt):
I agree with TIF, the tablet or smartphone pics are a lot more superior to scanning also a program (free) called PhotoJoiner will help you place them side by side, great coin by the way.
May you identify the person or deity on reverse. The letters S and C across fields refer to Roman or provincial coins?
It's a dupondius with Fortuna on the reverse. You can tell because she usually carries a rudder and cornucopia. Something like this one: https://www.acsearch.info/search.html?id=786867 Yours will be different depending on the acclimation titles.
7Calbrey, Jay GT4 was right on, & the illustration he provided looks pretty close to your coin. I took a quick peek at wildwinds.com & they illustrate an example from Roma Numismatics of RIC 893, that sold in 2009 that also looks close to your coin. See photo below. It appears there are many slight varieties to this dupondius.
