Roman Empire. Flavius Claudius Constantinus as caesar. Antioch Mint. Such coins were released at 330-334 A.C.
There is $100 worth of education in these if you got them unidentified and got to identify them all. After they are labeled, I would consider the value reduced. I am surprised there are so many fully identifiable but still low quality coins in one place. Perhaps the group started as a collection formed by a person who selected each individually from junk boxes for a few cents each over a period of time. There are a couple I would want to see in person before accepting as genuine but, as a group, Kentucky was correct:
I think that one may be a provincial issue. I think I see TEIN (from ΦΑVCΤΕΙΝΑ), not TIN, in the obverse inscription. Moreover, there is a dimple on each side from preparing the flan with a lathe before striking, as is common on provincial issues, but not done with imperial issues. Take another look at it.
This is actually Faustina II, the wife of Marcus Aurelius and the mother of Commodus. I have an example in my own collection: Faustina II, AD 147-175 Roman provincial AE 23.6 mm, 6.28 g, 6 h. Thrace, Pautalia, AD 147-175. Obv: ΦΑVCΤΕΙΝΑ CΕΒΑCΤΗ, bare-headed and draped bust, right. Rev: ΟVΛΠΙΑC ΠΑVΤΑΛΙΑC, Tyche standing left, holding rudder and cornucopiae.

Roman Empire. Emperor Flavius Victor (384-388). The son and co-governor of the emperor-usurper Magnus Clemens Maximus.
The "two-turret" PROVIDENTIAE gate coins date to the mid 320's, it was the run of centenionales which includes the 2-standard GLORIA EXERCITVS soldiers and standards and the VRBS ROMA and CONSTANTINOPOLIS city commemoratives (you have a Constantinopolis further down the thread) issued to commemorate Constantine I's moving the administrative capital from Rome to Constantinople which began being minted in 330 - which was the year the administration officially moved. These types, soldiers and standards and city commemoratives, were struck, with a couple of minor weight adjustments, until Constantine I's death in 337, then were all either continued or intermittently issued through the later 340's by his sons who succeeded him.
