So I have this strange coin for some time, which has only one printed side. It is impossible for me to understand what it is written on it because of my poor knowledge in the field on ancient coins. When I got it, the back of the coin was covered with some glue or tape. Maybe the previous owner placed it somewhere like on a wall or on an object and needed a way to mount it. I am not sure what is the metal that was made of, but doesn't seem to be bronze. Maybe silver? It doesn't seem to have any rust on it, but only a slight yellowish patina. It is 21 mm in diameter and weights around 4 grams. Do you think it is a real coin or maybe somebody tried to make a replica on an original one, but failed? I upload several pictures with the attempt to give you better perspective about the unclear letters on it. Is it a good idea to try to clean it in some way? There is still some glue on the back side.
