It is a worn Severus Alexander AE from Cappadocia, Caesarea with the Mt. Argeaus on an altar reverse. Although much of the legends are worn, it is fairly clear to the left of the bust, and as far as I can tell it is an error: AY K ЄC (error for CЄ). Is this the right conclusion, or do I have the wrong emperor, bad eyes, etc.? I just can't find any legends that match this, but the "CЄ" is correct for the common AEs of Severus Alexander.
