Left - I cannot distinguish anything on the obverse but the reverse is a fallen horseman type. Many rulers from Constantinian dynasty issues these. You can read about this popular type of coins on this page, written by @dougsmit https://www.forumancientcoins.com/dougsmith/fh.html Right - a Gloria Exercitus type (another popular coin). Mint is Siscia (visible in the exergue of the reverse) but I cannot distinguish the obverse legend. The ruler could be Constantine I or Constantius II but the similarity in name doesn't help when the legend is not clear. You can download the Excel file for these coins from here http://www.catbikes.ch/coinstuff/coins-ric.htm There is a distinct category of Gloria Exercitus coins and perhaps with the coin in hand you can narrow it down.
@ambr0zie Thank you! I will take advantage of the links you provided when I have time to sit and really work with them!
