GENIO POPVLI ROMANI portrait coins of the tetrarchies, arranged by mint.
Struck c. 294-306.
(To see them arranged by emperor, use these links: Diocletian, Maximian, Constantius, Galerius, or other later emperors.)
Click the image to see both sides of the coin.
All the mints for this type: London, Treveri (Trier), Lugdunum (Lyons), Ticinum, Aquileia, Rome, Siscia, Serdica, Thessalonica, Heraclea, Nicomedia, Cyzicus, Antioch, Alexandria. [Carthage and Ostia are also in RIC volume VI, but neither minted this type.]
Note: This page lacks images of at least a dozen common emperor and mint combinations. It does not mean they are rare; it just means I don't happen to have that combination to show here. Click here for a table listing all emperor and mint combinations.
