I noted only one obverse die, it is the same one used for the VICTORIA AVGG type and which seems unique to both types. For the reverse I noted two different dies.

I observe that on most of Pupienus' coins the cuirass is almost invisible and the shoulder appears smooth. Although I have listed a variant with a non-cuirassed bust for other emperors from the same period, this bust of Pupienus seems to be cuirassed. We see streaks indicating a cuirass in the lower shoulder or at least an irregular lower shoulder showing a desire to display a cuirass. Here is an example:
On this photo the streaks are visible at the bottom of the shoulder.
However, we cannot exclude that only draped busts exist. So far, I haven't noticed an example where the shoulder is undoubtedly smooth.
