First one is Maximian, probably a larger follis. Genio Populi reverse. Can’t ID exactly, but I bet it would fetch upwards of $20 on the open market if you’re lucky. second coin is a Middle Ages/medieval French or English coin. Values on these vary wildly so you’ll need a better expert than I for that
Go to Wildwinds.com if you want to take a crack at ID’ing the Maximian. look for the Antioch section and see if any of the Genio Populi entries match up
