The unusual reverse composition of this medallion, Juno Moneta flanked by Jupiter and Hercules, mimics the iconic "Tres Monetae" type. Jocelyn Toynbee suggests that this type was intended as "...a dedication of the imperial mint to the Emperors' heavenly patrons, who bless financial administration and reforms." A most probable explanation given Diocletian's tendency to celebrate the religious significance for almost every facet of his reign.
