A nice find. I think that I have another, clearer obverse die match, which is also relevant.
Obv:- IMP CAE L SEP SEV PERT AVG, laureate head right
Rev:- BONETAE AVG (sic), Moneta standing left, holding scales in right hand, cornucopiae in left
Minted in Emesa. A.D. 193
Reference(s) - RIC - (unlisted cf. 359A, which is scarce citing RD). RSC -. BMCRE - .

My BONETAE is useful to me as it provides a linkage to the AVG II C issue.0

which in turn has it's own MONETAE reverse

So MONETAE is not unexpected.
