Maximian Follis

Maximian's follis coinage was struck as part of Diocletian's landmark currency reform of 294 AD, and as co-Augustus governing the western provinces, Maximian's coins closely mirror those of his eastern colleague in design and denomination. His coinage offers a window into the western administration of the Tetrarchic system.

Collectors of Tetrarchic coinage often seek complete sets featuring all four rulers of a given period, making Maximian's follis a natural companion piece to those of Diocletian, Constantius I, and Galerius.

Maximian was a trusted military colleague of Diocletian, elevated first to Caesar and then to co-Augustus in 286 AD to help manage the empire's vast defensive needs, taking responsibility for the western provinces including Italy, Gaul, Spain, and Africa. He campaigned against various rebels and invaders in the west, including suppressing the Bagaudae uprising in Gaul and confronting the usurper Carausius in Britain.

As part of the Tetrarchy formalized in 293 AD, Maximian adopted the divine epithet 'Herculius,' associating himself with Hercules just as Diocletian associated himself with Jupiter, reflecting the ideological underpinning of their shared rule. Maximian abdicated alongside Diocletian in 305 AD but made several later, ultimately unsuccessful attempts to reclaim power, before his death (likely forced suicide) in 310 AD.

The obverse shows a laureate, cuirassed bust of Maximian, with legends such as IMP MAXIMIANVS PF AVG or later Maximianus-specific titulature reflecting his periods of active or retired rule. As with other Tetrarchic rulers, the general portrait style is quite similar across the group, so the legend is the primary means of identifying the specific emperor.

The standard reverse for his main reform-era coinage is GENIO POPVLI ROMANI, showing the standing Genius figure with patera and cornucopia, identical in general design to contemporary folles of Diocletian, Constantius I, and Galerius. Mint marks in the exergue identify western production centers such as Trier, Ticinum, Aquileia, or Carthage.

The coin matches the standard follis format of the reform period, roughly 25-28mm with a silvered bronze surface. Distinguishing Maximian's coins from those of his Tetrarchic colleagues depends entirely on careful reading of the obverse legend, since the reverse type and general fabric are shared across the group.

Maximian folles are common and generally affordable, with typical examples of the standard GENIO POPVLI ROMANI type often found in the roughly $20 to $50 range in circulated condition. As with other Tetrarchic folles, value is influenced more by mint rarity, officina, strike quality, and silvering preservation than by scarcity of the basic type itself.

Collectors assembling complete Tetrarchic sets often seek matching quality and preservation across Diocletian, Maximian, Constantius I, and Galerius examples, which can create modest premiums for well-matched, high-grade groups.
