Hello there, this is my first post as i recently started buying uncleaned ancient coins. I bought some in eastern Serbia, all of them are roman bronzes however one is very odd. As you can see on the photos, it's oval shaped and doesn't have a reverse at all. I cleaned it for 2 weeks in distilled water and it did reveal more detail but I simply cannot find any similiar coin. Any help would be awesome! Thank you guys.
Sorry for the picture quality it's my first time posting here, just in case i put on links to the full res images.
