Reverse

Jupiter standing left, nude but chlamys over left shoulder, holding on right hand a small Victory on globe and with left hand a long sceptre; at feet left, eagle left, head right looking upward, a wreath in its beak.
Officina mark in right field; mintmark in exergue.

Script: Latin

Lettering:
IOVI CONSERVATORI
B
SIS

Translation: Jovi Conservatori: "To Jupiter the Protector".

Comment

This variant differs from the earlier types mainly by having the small Victory on globe instead of a thunderbolt on reverse.

Two reverse caesurae are known for this variant:
  • IOVICON - SERVATORI
  • IOVICONS - ERVATORI

Interesting fact

One interesting fact about this coin is that it features an image of the Roman god Jupiter on one side and the emperor Constantinus I on the other, highlighting the blending of Roman paganism and Christianity during this period.
