Since it's your first post, welcome to the site.
We usually ask for measurements along with the photos, at least the diameter.
For the second coin, the emperor name looks unreadable but the reverse with a soldier is undoubtly FEL TEMP REPARATIO.
For the third coin, the reverse with the campgate appears to be GLORIA REIPVBLICAE, only two examples on our catalog.
I'm going by the second one since I've found a partial name along the emperor head:
N#376590
Your first coin is the most worn of the three, only silhouettes visible. We need measurements to help narrowing the search.
