The reassignment of this peculiar issue to the end of the reign of Gallienus as opposed to the traditional placement during the interregnum between the death of Aurelian and the elevation of Tacitus has been convincingly argued by David Yonge. He bases his determination on flan manufacture, portrait style and a comparative analysis of mid-third century Roman monetary denominations, and suggests that this issue was probably a commemorative issue in anticipation of Gallienus’ entry into Rome after his victories over the Herulians and Goths at Naissus.
