Well, if it's Greek that'd be a good reason for its not looking very genuinely Roman!
So Aeolis, Kyme, BMC 120, similar to the semi-autonomous issue cataloged as BMC 118, except it's slightly larger & heavier, and Tyche on the obverse faces left rather than right. Might well be from the same time period, though, which would be 253-268 AD.
