RIC IV.1 Caracalla 6, page 212. Plate 11.10 (is much worse). BMC V 193-196, plate 10.7 (also much worse). This type almost aways has a small flan with much of the legend off.
Caracalla was about 10 years old when this type was minted. He was made Caesar in 196 which meant he was in line to be the next Augustus, but this type, unique to Caracalla, makes it explicit.
