Roman Imperial coin, bronze, follis. Struck during the reign of Gaius Aurelius Valerius Dicoletianus Augustus (Diocletian), 295-305 C.E. The laureate head of Diocletian faces right in profile, on obverse with the inscriptions "IMP C DIOCLETIANVS P F AVG" surrounding image. On reverse, the standing figure of Genius (the individual instance of a general divine nature that is present in every individual person, place, or thing) faces left and holds a patera in his left hand and a cornucopia in his left with the inscriptions "GENIO POPVLI ROMANI" surrounding image, "S-(gamma)" on left and right of image. Reverse image slightly off struck.
Date range: 295-305 C.E.
Remarks: Diocletian instituted a number of coin reforms. Coins resembling antoniniani continued to be struck but they contained no trace of silver, whereas the pre-reform antoniniani contained 4% of that metal. The absence of the XXI mark on these post-reform radiates and the transference of this mark to the follis, which contained a small percentage of silver, lends weight to the theory that the true meaning of the XXI mark, introduced by Aurelian, is 20 parts of copper and 1 part of silver. Diocletian's coins were minted in London, Treveri, Lugdunum, Ticinum, Aquileia, Rome, Carthage, Siscia, Serdica, Thessalonica, Heraclea, Nicomedia, Cyzicus, Antioch, Tripolis, Alexandria, and possibly Clausentum.
