I need your help again, please [επιλυμένο]

Hi there, I have another coin to identify please

The diameter is 22 mm

Thanks

As far as I know, it is an antoninianus, but I can't quite identify the ruler (Maybe Trajan Decius or Valerian ; but I would not bet on it). I could not decipher the Latin inscription on the reverse either ( last word is REPVBLICE). Nevertheless, I hope that I have been able to help at least a little.

This is an antoninianus of Trebonianus Gallus, with “LIBERTAS PUBLICA” on the reverse. It is relatively easy to read “TREB” above the portrait on the obverse

N#283583

Thank you very much for your help

To be honest,  ii am not use to it to read coins of that age,   iit was just accumulating  ffrom small lots from fleemarkets or freebees when i bought something else.  IIm sorry if im a novice in that field but in my country are not many of that coins, 

But im happy about the great help

Thanks again
