I don't know much of anything about identifying ancient coins. I have a bunch that were pulled from various foreign coin lots. Wondering if any of you ancient coin collectors here can help me identify them. Also, are any of them better ones? Photographed them in pairs to keep the pictures fewer. The first two are around quarter size, the rest are smaller. Thanks!
The last one with the helmeted Roman and "angel" on the back looks like a Constantine the Great, Constantinopolis Commemorative, of Lyons (mintmark PLC)
