As or Dupondius?

So are the "brassy" colored coin sof Augustus (DIVVS AVGVSTVS PATER, radiate head right / S-C either side of large altar with closed doors, PROVIDENT below, ) Ases or Dupondii? I've seen both used, but more seem to de described as Ases; I also refer to them as an As.

I don't see any picture (purposely ?)
The one you refer to, Randy, although Augustus is wearing a radiate crown, is an As. The radiate crown isn't here intended to signify "double" but "consecration"
