Roman coin identification? [решено]

Hi everyone! I need your help.
I think it's a roman coin. Seems authentic, but I don't know. The only thing I know is it's diameter and weight.
Diameter: 15 mm
Weight: 1.08 g

Any help will be appreciated.





UPDATE

Denomination: AE4
Metal: Bronze
Emperor: Constans I
Obverse: CONSTANS PF AVG
Reverse: VICTORIAE DD AVGG Q NN
Mint: Siscia maybe?

Welcome to Numista!

Yes, it's a 4th-century Roman bronze coin. It is authentic, but unfortunately, in this condition it has no numismatic value. There are very common and can be obtained for a few dollars or euros in reasonably good condition.

I have searched it on Google, based on what you said. And I realized that my coin is very similar to this:
