Lugdunum Mint

Lugdunum (modern Lyon, France) was the principal western imperial mint from Augustus through the early second century, and one of the most important mints in Roman numismatic history. Augustus established it as the sole mint for gold and silver coinage in the western provinces, a monopoly it held for extended periods under Augustus and Tiberius. The mint's output under these early emperors is massive and well-studied, with distinctive portrait styles that differ noticeably from later Rome-mint work. Lugdunum aurei and denarii of Augustus are among the most commonly encountered precious-metal coins of the period. The mint produced base metal coinage as well, including the well-known Altar of Lugdunum asses and the portrait asses of the Julio-Claudian dynasty. After the first century, Lugdunum's role diminished as Rome reasserted central control, though it was revived intermittently during the third-century crisis. The mint was eventually supplanted by Arelate (Arles) in the early fourth century. Lugdunum's mint mark is typically LVG or PLG on later issues. For collectors, Lugdunum denarii and aurei of the Julio-Claudian period are a core collecting area, with distinctive die work and well-documented sequences. The standard reference is RIC I (second edition) for early imperial issues.
