*Julia Mamaea, mother of Severus Alexander (222-235), aureus, Rome, 222, ivlia mamaea avg, draped bust right, rev., ivno conservatrix, Juno standing left holding patera and sceptre and with peacock at her feet, 7.29g (RIC 342; C. 6; Calico 3152), has been cleaned, about very fine, extremely rare Although there are no obvious edge marks to denote that the coin has been mounted, its appearance and provenance suggest that at some stage it might have been. It formerly belonged to a family jewellery business in Carlisle and the Department of Coins and Medals at the British Museum has records of having examined it on 6th July 1933 and again on 16 January 2003. The BM retains a plaster cast of the coin from when it was shown there in 1933. Julia Mamaea, who wielded political power over her son Severus Alexander, fell foul of the military and both she and her son were murdered on the instigation of Maximinus Thrax in 235. While her silver and bronze coins are common her gold coinage is extremely rare. (£10000 - 15000)
