The top coin looks like a Sestertius of one of the Antonine Emperors. You should also post images of both sides of that small silver medieval coin.
The big one looks like Marcus Aurelius. The small Roman probably Constantius II. Someone will come along and help you with the Medieval silver coin.
Constantius II Alexandria Rev....VOT / XX / MVLT / XXX in four lines within wreath; SMAL Gamma in exergue
The second coin is a small bronze of Constans from the Alexandria mint (you can tell that's him and not Constantius II due to the spacing between the letters). Unfortunately I can't help you with the rest.
Echoing others: marcus Aurelius sestertius Constans VOT. Great shape, Alexandria mint (SMALT - Sacra Moneta Alexandria Tertium) sacred money of the third officina of the Alexandria mint and a medieval
Usually Constans is CONSTA-NS, or CONSTAN-S whereas Constantius II is usually CONSTAN-TIVS Also, since Constantius is a longer name the letters tend to be smaller and closer together. The way I see if if the left hand letters of CONSTAN looks large, then it’s probably not C-II
Welcome to the neighborhood, Jill! It looks like you posted the same images in three different forums. It's only necessary to post in one forum where you can ask multiple questions. It's no big deal, but I thought this might help you in the future. ~Chris
I have asked for this thread to be moved to Ancients section. You will get more views and responses from the very knowledgeable people there. Wecome to CT
Indeed, multiple threads about the same coin(s) are a no-no. I have merged them all together here, in the Ancients thread, which is why there is some duplication.
The medieval coin looks to be continental European rather than English. Maybe 13th-14th century, would be my wild guess. That appears to be a lily cross (cross fleurée) on the reverse. There is a fleur-de-lis on the obverse above the central lettering. The fleur-de-lis often indicates France, but I can't say that for sure in this case, as I'm out of my depth. I can't make much out of the lettering, but someone here might be able to ID it, perhaps @FitzNigel or @TheRed or one of our other resident medievalists. I'm only a mere dabbler in such things.
I believe I have found a possible match for that small medieval silver coin. https://en.numista.com/catalogue/pieces33586.html
Nicely done! So it seems I was right about 13th-14th century France, but was unfamiliar with the type.
