The radiate or Post-reform radiate (the actual name, like many Roman coins of this time, is unknown), was introduced by Diocletian during his reforms. It looked very similar to an Antoninianus even with a radiated crown like Sol Invictus, except it misses the XXI that numismatists believe was to represent 20 parts bronze to 1 part silver. The radiate had little or no content of silver. The weight varies between 2.23[1] and 3.44 grams.[2]
Only one image is defined on coins found Jupiter presents Victory on a globe to Diocletian (Wildwinds[3]) with the mintmark in between the human images[4]
