Identifying roman coin (bad quality) [решено]

Hello, 

I need help identifying another roman coin, again. Due to the condition, I unfortunately did not succeed in identifying the coin (Is it a coin of Hadrian probably?). I apologise for the poor condition of the coin.

Thanks in advance.

Diameter: 19 mm

Weight: 5,6 grams

Maybe septimius severus,hard to say,very bad condition…
