Looking at my coin in-hand, I think the reverse die is identical to the one you posted Biancasdad. Spacing of the lettering, the design, lettering relative to the design... it matches.
After some research I found two types that are nearly identical except for the obverse inscription. One is MAVS ANTONINVS PIVS AV GER CM and the other is the one you posted; MAVBEL ANTONINVS PIVS AVG PBG MAX. I cannot make out the obverse inscription on my coin well enough to tell the difference but since the reverse is identical to the one on acsearch, it's probably that type.
