Please give dimensions, weight and provenance, thanks ! It would be easier to ID. It's probably a coin of Elagabalus minted at Marcianopolis under the magistrate Julius Antoninus Seleucus.
Based on the inscription on the reverse it looks like Moesia Inferior, Marcianopolis. The obverse is to worn for me to confirm which type but this narrows it down: https://rpc.ashmus.ox.ac.uk/search/...olis+holding+cornucopia+and+patera+bust+right
