One of my recent acquisitions is this bronze coin of Philip I. It has Liberalitas on reverse and weighs 2.86 g. Listed RIC 38b in Rome, it's considered only as a silver Antoninianus or Denarius. But mine is of Bronze. Can't find a match or exact attribution. Thanks..
Virtus is female (along with Roma) and is depicted exposing the right breast with lowered drapery. The figure here is fully covered and is either Mars, a Solder or the Emperor in Military dress. The depiction here is entirely consistent with Mars the Peacemaker. We do not only have coins as our base of reference. We have statuary too depicting Mars, where he is often depicted in full military dress, which include a shield. I am thinking of a depiction such as this from the Capitoline Museum.
