Julia Mamaea Silver Denarii, Authenticated Severan Coinage AD 222 to 235

Julia Mamaea was, for thirteen years between AD 222 and 235, the de facto ruler of the Roman Empire. Her son Severus Alexander reached the throne at thirteen, and Mamaea — daughter of Julia Maesa, niece of Julia Domna — ran the household, the imperial finances, and through them the day-to-day business of empire. When Maximinus Thrax's troops murdered them both on the Rhine frontier in March AD 235, three and a half decades of Severan rule ended. The dynasty's silver coinage is one of the densest visual records of that period that survives.

This collection is the surviving Julia Mamaea silver denarii in Aurora's current stock. Five pieces, all silver, all struck (not cast), all catalogued against Roman Imperial Coinage, all reviewed by an independent numismatist, all backed by Aurora's written lifetime authenticity guarantee.

Why Julia Mamaea coinage matters

Mamaea's silver denarii are among the most-collected Severan-period coins for three reasons. First, the portrait. A Mamaea obverse shows the characteristic waved coiffure of late-Severan court fashion, with the rolled fringe pulled back from a high forehead and the bun coiled tight at the nape. The portrait is consistent enough across the issue that die-style differences are clearly visible to a careful eye — useful both for attribution and for spotting modern forgeries that copy a single auction-house photograph and miss the variation.

Second, the reverses. Mamaea's silver carries a recurring vocabulary of imperial virtue and female deity: Pudicitia (modesty), Felicitas (good fortune), Venus Genetrix (Venus the Mother), Juno Conservatrix (Juno the Preserver), Vesta, Annona. Each reverse is a deliberate statement of the kind of woman the imperial mint wanted Roman silver to show — and by extension, the kind of regency Mamaea projected.

Third, the weight and fineness sit at a transitional moment. Mamaea's denarii weigh approximately 2.4 to 3.0 grams at a silver fineness of around 45 to 55 percent — well below the early Imperial standard but still unambiguously silver. After Severus Alexander's murder the silver denarius would not last another decade as the empire's standard coin. Mamaea's silver is, in retrospect, near the end of the classical denarius tradition.

What to check on a Julia Mamaea denarius

Three signals separate a collectible Mamaea denarius from a worn or problematic one. The portrait should show individual modelling of the hairstyle and facial features — a flat or generic profile indicates either heavy circulation wear or a poor die. The obverse legend will run IVLIA MAMAEA AVG, with letterforms consistent with the Rome mint of the 220s; spacing errors or anachronistic letter shapes are warning signs.

The reverse should match a documented RIC type. Aurora's catalogue references the relevant entry on every listing: RIC IV 348 (Venus Genetrix), RIC IV-2 341 (Felicitas), RIC IV-2 335 (Vesta), and others. A reverse that cannot be matched to a published type is worth a closer look. The full check sits in our guide on the seven authentication markers we apply to every Severan coin, and the inscription glossary is in our guide to the letters on Roman coins.

Why buy a Mamaea denarius from Aurora rather than a marketplace

Two reasons. First, the work that has already been done before the coin reaches the listing page: seven antiquarian markers, RIC reference confirmed, OCRE cross-reference where applicable, independent numismatist sign-off on file. Second, the lifetime authenticity guarantee in writing: if a Mamaea denarius bought from Aurora is ever shown to be inauthentic, we refund it. Forever.

All five Julia Mamaea coins in this collection are catalogued, photographed obverse and reverse at 2048 px, and ship insured worldwide from Belgium. Provenance documentation accompanies every order.
