Need Help To ID These Three Coins

#1: Emperor Elagabalus, a dupondius judging by the spiky headgear. Reverse MARS VICTOR, Mars walking with spear and trophy. Sear lists a sestertius and an as with this design, but not a dupondius; none of the copper Mars coins are no Wildwinds.

#2: Emperor Tiberius, an as, but the large letters SC normally on either side of the seated figure appear to be absent. Example.

#3: Emperor Severus Alexander, an as, reverse PM TRP VIII COS III PP, emperor in "slow, decorated quadriga". This example is in much better condition.

I have to say, the second and third look decidedly suspicious to me; they might be cast counterfeits.
