 A Coin Fit for an Emperor: Design and Quality

Struck in the mid-4th century AD, this AV Solidus was issued under the reign of Emperor Constans, the youngest son of Constantine the Great. The coin celebrates Constans' 10th year of rule—an event marked by victory, religious consolidation, and empire-wide stability (at least on the surface).

Obverse Design:
The obverse features a regal bust of Constans wearing a pearl-diademed crown and imperial military attire. The surrounding legend reads “CONSTANS AVGVSTVS”—a proud statement of imperial authority.

Reverse Design:
The reverse is symbolic and celebratory. Two winged Victories stand opposite each other, holding a shield inscribed with “VOT X MVLT XX”—a promise to rule for 10 years, with wishes for 20. Around them, the inscription “VICTORIAE DD NN AVGG” translates to “Victory of Our Lords the Emperors,” emphasizing joint rule and divine sanction.

Mint & Quality:

• Minted in Treveri (modern-day Trier, Germany)

• Graded MS (Mint State) 5/5 Strike, 4/5 Surface by NGC

• Weight: Approx. 4.49g of high-purity gold

• Diameter: Approx. 21.5mm

The coin exhibits exceptional detail, sharp strike, and near-pristine preservation—a true marvel considering its 1,670-year history.

 A Brief History of Emperor Constans and His World

Constans (Flavius Julius Constans) came to power in 337 AD after the death of his father, Constantine the Great, the first Christian emperor. He inherited the western part of the Roman Empire—including Italy, North Africa, and Gaul—and quickly demonstrated his military prowess by defeating his brother, Constantine II, in a power struggle in 340 AD.

Known for his strong Christian faith, Constans supported Orthodox Christianity and opposed paganism and Arianism. He issued edicts banning non-Christian sacrifices and supported the restoration of exiled bishops. In 343 AD, Constans made a rare and historic imperial visit to Britain—the last Roman emperor ever to do so.

But his rule was short-lived. In 350 AD, he was overthrown and killed during a coup led by the usurper Magnentius, ending his reign abruptly at just 27 years old.

This coin—struck circa 347–348 AD—represents Constans at the height of his power, projecting strength, victory, and continuity. It’s a golden relic from a time just before the empire's political fractures became irreversible.

Rarity, Market Value & Investment Potential

Why is this coin a standout in the numismatic world?

• Gold Solidus coins are rare. Most Roman coinage was minted in bronze or silver. Gold coins like this were reserved for major state payments, military bonuses, or imperial ceremonies.

• State of Preservation: With MS-grade certification and outstanding eye appeal, this particular example is at the top percentile of known specimens.

• Historical Weight: Not only is it a beautiful artifact, but it also marks a critical moment in imperial Roman history—the declining years of a dynasty and the shift toward ecclesiastical influence in politics.

Auction Value:
In June 2025, this coin sold at MDC Monaco for ¥733,597 (approx. $4,800 USD) after a competitive round of bidding—well above its initial estimate.

Long-Term Potential:

• Gold content offers intrinsic value.

• Roman solidi have shown steady appreciation in both private sales and international auctions.

• Coins of this caliber and condition often disappear into private collections for decades, rarely reappearing on the market.

Final Thoughts: Holding History in Your Hands

For collectors of ancient numismatics, the AV Solidus of Constans offers the perfect convergence of art, rarity, and history. It's not just a coin—it's a statement piece, a conversation starter, and a timeless asset.

As demand grows for tangible heritage and inflation-resistant investments, owning a piece of imperial Rome has never been more compelling. Whether you admire it as a beautiful work of classical engraving or a hedge against market volatility, this coin offers enduring value.
