I think you may have some very worn ancient coins. I wonder if one of the mods can move this to the ancients forum maybe where the OP can possibly get some better answers? Whatcha think @lordmarcovan ?
Yeah, it could be moved. But if it was left here, somebody will answer. And then all the folks who read this section of the forum, but don't ever read the ancients section, might learn a little bit about coins like these. And who knows, some may even decide they have an interest.
One is a Roman Provincial, but the photos are to far away to determine who One is Hieron II: https://www.acsearch.info/search.ht...de=1&fr=1&it=1&es=1&ot=1¤cy=usd&order=0 One is a Late Roman Bronze, most likely a follis. Again I cant tell who it is because the photo is too far away; @Victor_Clark probably knows who it is. The first two in their condition are not worth much $5-$10 The Late Roman Bronze looks to be EF (XF) and is worth $20-$25 if it's a common coin, more if it's a scare emperor or type.
