IMP C M AVR SEV ALEXAND AVG, laureate and draped bust right, seen from behind.

Not in RIC for Antioch mint. cf RIC IV 139A and 194; BMCRE 737 and RSC 57 (Rome)

RSC states that the coin RIC refers to does not exist.
From a Sev. Alex Collector: "This coin is not listed in RIC 
as coming from Antioch. But the uneven obverse lettering is 
an obvious Antioch characteristic."
