Elagabalus, 218-222, AR denarius, Mint of Antioch, 218/19 AD.
Obv: ANTONINVS PI]VS FEL AVG laureate, draped and cuirassed bust of Elagabalus right, seen from behind (we can’t tell if he’s wearing the infamous “horn” or not, it would have been on the chip if it were in the original portrait)
Rx: FORTVNA REDVX Fortuna seated left holding patera and cornucopiae, wheel beneath seat.
RIC IV 189; RSC 47a
The chip appears to be modern – probably from a plow-strike.
