Remarks
The coinage of Septimus Severus is divided in 3 iconographic groups : the coins with the portrait of Septimus Severus (subdivided in 3 issues dated in 198-204/5 AD, 204/5-209/10 AD and 209/10-211 AD), those with the portrait of Caracalla (subdivided in 3 issues dated in 198-204/5 AD, 204/5-209/10 AD and 209/10-211 AD) and those with the portrait of Geta (subdivided in 2 series). The average weight is approximate: 5,18 g for the coins with Edessa and 5,39 g for those with the goat. Metrology p. 189-209.
