C'est une monnaie de Constantin II frappée dans l'atelier de Rome : https://www.nummus-bible-database.com/monnaie-97364.htm ?

c'est une copie chinoise en porte-clé d'un rouble de 1912 https://fr.numista.com/catalogue/pieces16517.html je ne sais pas si la notion d'état a un sens dans ce cas-ci, peut-être SUP mais on ne peut pas dire que la chose soit aussi soignée, et de loin, que l'original. valeur 1 euro.

Hi! It's a nummus with two roman soldiers holding a spear at the reverse side. Two standards are positionned between the soldiers. The reverse legend is "GLORIA EXERCITVS". The workshop where the coin was stroke is indicared below the soldiers but the quality of your picture is not sufficient to read it. Perhaps some of the colleagues of the forum having eagle eyes could read it. For the obverse the emperor could be constantine the great or constantine ii. A more detailed picture might help to clarify it. If you want to check other examples there are some in the link below: some other examples Regards!
