Provincial AE with Countermark

I picked up this unidentified Provincial coin with interesting countermark from an auction in December and am just now getting around to trying to identify it. Was only listed by size and weight.

AE Bronze (28.9mm 14.79g)

I thought it was an earlier Imperial, but others have suggested Elegabalus/Carcalla time frame. Does seem to be Homonoia on the reverse.

And who would be on the countermark?

First need to find the Emperor and the deity on the rev. holding the cornucopia. Doing a lot of searching on aesearch. Gallienus? Caracalla? Geta? 20s-30s clean shaven. Head shape is not matching and there isn't enough text.

 

have a look at: https://auktionen.gmcoinart.de/Los/142/552.0 the reverse is very similar
