MIR (p. 79) suggests that this single reverse die, used for both Valerian and Gallienus, may have been prepared for striking sestertii for Cornelia Supera, wife of Aemilianus, but never used for this purpose. Reverses depicting Vesta are certainly found more frequently on coins issued for empresses than for emperors.
