Severus Alexander Coins: Denarii, Reign & Collector’s Guide
Severus Alexander: The Last Emperor of the Severan Dynasty
AD 222 to 235, the young emperor before the Crisis of the Third Century.
Severus Alexander ruled at the end of the Severan dynasty, just before the political and military instability conventionally called the Crisis of the Third Century.
Ascending to the throne as a teenager, Alexander ruled during the final phase of the Severan dynasty as pressure mounted on Rome's eastern and northern frontiers.
His coinage gives collectors an unusually broad window into the period: denarii remained abundant, large imperial bronze was still issued, and provincial mints produced a wide range of local types.
The Rise and Fall of Severus Alexander
Severus Alexander was born around AD 208 in the city of Arca in the Roman East and belonged to the Severan imperial family through his mother Julia Mamaea and grandmother Julia Maesa. After Macrinus was overthrown, Alexander's cousin Elagabalus became emperor. As Elagabalus lost support, Julia Maesa helped arrange Alexander's adoption and elevation as Caesar. After Elagabalus was killed in AD 222, the young Severus Alexander was proclaimed emperor.
Later ancient sources often portray Alexander as moderate and deferential to the Senate, but those accounts are shaped by literary convention. Julia Mamaea and senior advisers exercised substantial influence over the young emperor's government. His reign faced major external pressure from the new Sasanian Empire and from Germanic groups on the Rhine. In AD 235, during the German campaign, Alexander pursued negotiation before a major battle and was accused by hostile troops of preferring payments and diplomacy to decisive fighting.
Near Moguntiacum in AD 235, mutinous troops killed Severus Alexander and Julia Mamaea and acclaimed Maximinus Thrax. His death ended the Severan dynasty and is commonly treated as the opening of the Crisis of the Third Century.
What Coins Did Severus Alexander Issue?
His reign produced abundant silver denarii, gold aurei, large base-metal denominations such as sestertii, and extensive provincial coinage.
- Silver denarius, the most familiar denomination, with youthful laureate portraits and reverses featuring deities and virtues, abundant and approachable
- Gold aureus, prestigious gold issues carrying many of the same imperial portrait and reverse themes seen across the reign
- Sestertius, large base-metal coins with broad flans that can preserve impressive portraits and reverse designs
- Provincial coinage, extensive across the Greek-speaking eastern provinces, with local deities, civic types, and regional portrait styles reflecting active provincial minting networks
How to Collect Severus Alexander Coins
Most standard denarii of Severus Alexander are not rare, which is one reason the emperor remains popular with collectors. Because many survive in collectible condition, buyers can be selective about portrait quality, centering, surfaces, and reverse detail.
Start here. Look for a silver denarius with a clear portrait, centered strike, attractive surfaces, and an identifiable reverse.
Go deeper. Pair Severus Alexander with Elagabalus, Julia Mamaea, and Maximinus Thrax, or build around portrait development, reverse themes, and provincial issues. The most direct pairing is with his mother Julia Mamaea, the true power behind his throne, who governed alongside him until they were killed together in AD 235.
Severus Alexander is the emperor whose death marks the boundary between two worlds: the relative stability of the Severan dynasty behind him, and the half-century of near-constant civil war, invasion, and economic collapse ahead. His coins are abundant, affordable in most grades, and among the most approachable Severan issues for new collectors, yet they carry the weight of a genuine turning point in Roman history. When the troops killed the young emperor and his mother at Moguntiacum, they did not just end a dynasty. They opened the Crisis of the Third Century.
