Sestertius of Maximinus Thrax

The sestertius of Maximinus Thrax is a large brass-and-bronze Roman coin struck during the brief reign of Emperor Gaius Julius Verus Maximinus (235-238 AD), remembered as the first of the "barracks emperors." It is one of the largest circulating denominations of the Roman Empire, typically measuring roughly 28-32 mm across and weighing on the order of 17-25 grams.

The obverse shows the emperor's bust facing right, usually laureate and draped or cuirassed, surrounded by an abbreviated Latin titulature. The reverse carried a personification or slogan reflecting the priorities of a regime built on the loyalty of the army, and Roman bronze coins of this period nearly always bear the letters SC (Senatus Consulto). Because Maximinus reigned only about three years, his sestertii are a compact and popular window onto the crisis-era coinage of third-century Rome.

Maximinus Thrax rose from the ranks of the Roman army and was acclaimed emperor by the troops in 235 AD after the murder of Severus Alexander, marking the start of the turbulent period often called the Crisis of the Third Century. Of provincial Thracian origin, he was the first emperor who had not entered the Senate before taking the throne, and he spent much of his reign campaigning on the Rhine and Danube frontiers rather than in Rome.

His coinage, produced at the mint of Rome, projected military strength and imperial virtues to fund and reward the legions. Sestertii were struck in substantial numbers during his short reign but were cut off when he was killed by his own soldiers at Aquileia in 238 AD, during the chaotic "Year of the Six Emperors." As a result, his large bronzes belong to a narrow, well-defined window and are closely associated with the story of the soldier-emperors.

Look first at the size and fabric: a genuine sestertius is a heavy, broad bronze coin, far larger than the smaller silver-washed or silver pieces of the same emperor. The obverse of this type shows a right-facing bust of Maximinus, laureate and typically draped and cuirassed, with a strongly modeled, realistic portrait featuring a prominent jaw and heavy features.

The surrounding obverse legend is an abbreviated imperial title, commonly rendered as IMP MAXIMINVS PIVS AVG or a close variant. Reverse designs vary by issue and usually depict a standing personification or the emperor, with a short slogan such as FIDES MILITVM, PAX AVGVSTI, PROVIDENTIA AVG, SALVS AVGVSTI, LIBERALITAS AVG, or VICTORIA GERMANICA. Nearly all reverses include the letters S C in the field or exergue, confirming a senatorial bronze denomination rather than an imperial precious-metal coin.

Sestertii of Maximinus Thrax are relatively available for a third-century large bronze, so value is driven mainly by condition, portrait quality, surface preservation, and reverse type. Heavily worn or corroded examples with soft detail sit at the low end, while sharply struck coins with clear legends, attractive patina, and a bold portrait command substantial premiums.

As a general guide, well-worn but identifiable pieces trade at modest hobbyist prices, mid-grade coins with pleasing surfaces reach into the mid range, and exceptional high-grade examples with fine style and glossy patina can be worth many times more. Certain scarcer reverse legends and superior artistic portraits add further premium. Because grade and eye appeal swing prices so widely, compare recent auction results for the same reverse type and condition rather than relying on a single figure.
