Hello,
I would have a correction and an additional entry to:
Denarius - Caracalla PONTIF TR P XI COS III PROF
This coin is also in my collection but has a different weight than stated in your description:
“Mass varies: 2.92–3.82 g;”
My coin has a weigth of 2,24g
Additional entry to the description of the revers:
"Lettering: PONTIF TR P XI COS III PROF
Translation:
Pontifex [Maximus], Tribunicia Potestate Undecima, Consul Tertium, PROF
[High] priest, holder of tribunician power for the eleventh time, consul for the third time, PROF"
PROF stands for “Profectio” and means “departure / march-off”
Picture of my coin:


Kind regards
