Being a one-per-ruler collector, I am keen to own a portrait of every Roman personality. One personality I don't yet have is Caligula's fourth wife Caesonia. The most common coin supposedly with her portrait is this one: Caligula & Caesonia Æ27 of Carthago Nova, Spain. C CAESAR AVG GERMANIS, laureate head right / DN ATEL FLAC CN POM FLAC II VIR Q V I N C, head of Caesonia (as Salus) right, SAL AVG across field. SGI 419. Caesonia isn't named, yet the female portrait is given the attribution of "Caesonia as Salus". So i am very curious... why should this be attributed as the portrait of such an ephemeral person as Caesonia?? Could the commonly accepted attribution be wrong? Could this is in fact be Salus AS Salus?
