Traditionally these coins have been described as asses because their appearance is similar to the last true asses struck during under Valerian and Gallienus, and are made of copper, however most recent scholarship identifies them as reduced sestertii since inflation had rendered the as an irrelevant denomination, yet the sestertius still remained as the acknowledged unit of accounting. A monetary reform was carried out in 274 AD, introducing new bronze coinage, with sestertii bearing a laureated portrait, and double sestertii (obverse bearing radiate portrait of Aurelian, reverse bearing portrait on moon crescent of Severina).[after NAC]
