P SEPT GETA CAES PONT 
LIBERALITAS AVGG V 

unlisted in RIC, but there is a clue in a note on RIC 88 of Geta... 

The common variety RIC 88 (RSC 68) is P SEPT PIVS AVG BRIT / LIBERALITAS AVG V, Liberalitas
standing left holding abacus and cornucopiae. 

The note in RIC (also RSC 68b, and not given a price), says: 

"Variant of obv. P SEPT.GETA.CAES.PONT., bust, draped, head bare, r., Mouchmov, Reka Devnia, p.119:
hybrid?" 

The reverse of Caracalla's RIC 136 (illustrated in RIC
and looks just like your reverse!) with the reverse of Caracalla's RIC 137 (bust of Geta with that inscription). 

I can see how a mint worker might make that mistake....
