Object type certainty: Certain
Workflow status: Published Find published

A lead alloy gilded Roman possible contemporary copy of a nummus of Diocletian.

Obverse inscription: IMP DIOCLETIANVS P AVG

Obverse description: laureate head left

Reverse inscription: MAXIMI[NVS] NOB CAES

Reverse description: Bust helmeted and laureate, spear or sceptre on right shoulder and shield on left shoulder

There seems little doubt that the reverse legend would have been MAXIMINVS rather that what might have been expected MAXIMIANVS, as the letter following the second I is almost certainly an N rather than an A and there is insufficient space for the longer name.

The obverse legend was used for Diocletian from c.294 to before 1 May 305, that for Maximinus from after 1 May 305. The obverse matches the style and typology of early nummi from Trier (c.298-9), cf. RIC VI, p. 182, no. 185a or p. 187, no. 299,). The reverse is probably based on a prototype from Aquileia (305-307), cf. RIC VI, p. 320, no. 68b or p. 323, no. 100a.

This piece is made by casting two different nummi and could only have been produced from the elevation of Maximinus in AD 305. Casting moulds of the tetrarchic period are known from Duston yet due to its methods of production it seems unlikely to be a cast copy of a nummus designed defraud.

The gilding suggests that this could be a plated copy of a gold aureus or medallion although at present this is uncertain. If the copy is intended to be a coin or medallion it would have to be of the weight of a double aureus.

A silver medallion in Paris is discussed in RIC Vol VI, p. 241 with the obverse inscription IMP DIOCLETIANVS AVG Bust laureate and cuirassed left and the reverse inscription MAXIMIANVS NOB CAES Bust laureate right.
