I recently decided to purchase some uncleaned coins. After some time soaking in distilled water and picking at them, some of them came out fairly well. Issue is that I'm having some trouble identifying some. Two of the coins I'm not sure if these are Arab imitations of Constans II or not. The smallest coin had a small bearded bust and what I am presuming is an incuse. The next coin I could only make out what looks like the bust of Apollo. Not sure what the reverse represents. The only one I am for certain would be this Pontus Amisos coin, but I do wonder if there's a way to make the figure of Nike more visible? This is my first time posting on the forum. I've been lurking for around a year about now, but I never got around to sharing my collection due to being busy with school.
Your coin on the left is an official issue of Constans II - Sear 1005 - Reginal Year 6 or 7. The coin on the right is probably also a Constans II official issue. I'm leaning towards Sear 1007, but it is tough to tell from all the overstriking.
