Between the death of the father and the assassination of Geta towards the end of 211, Caracalla's portrait remains static with a short full beard while Geta develops a long beard with hair strains like his father. The latter was a strong indicator of Geta's effort to be seen as the true successor to their father, an effort that came to naught when he was murdered. Caracalla's presentation on coins during the period of his co-reign with his father, from 198 to 210, are in broad terms in line with the third-century imperial representation; most coin types communicate military and religious messages, with other coins giving messages of "saeculum aureum" and virtues.
