Claudius II - Antoninian Identification!

I recently thought I'd research this coin, but I can't find out what it exactly is so I need your help! All I know is that it is a Claudius II - Antoninian/Gothicus. Im certain of that the type is a IMP CLAVDIVS PF AVG - FORTVNA REDVX but I'm very unsure about the exact mint. The coin does not have any mint, only a fortuna standing left, holding rudder and cornucopiae on the reverse and no dots beneath the bust on the obverse. It weighs 3.2 grams, has a diameter of c. 19 mm and a thickness of c. 1.8 mm. Luckily it is in very good condition so ID'ing it should be possible.



If you have any clue or suggestion on the mint and value please let me know!
