Justinian I Coins: Small Masterpieces from Byzantium’s Greatest Emperor

There’s something almost surreal about holding a solidus of Justinian I coins. Think about it: this tiny disc of gold — barely the size of a dime — may have once helped pay the wages of a Roman general, financed the glittering dome of the Hagia Sophia, or crossed enemy lines as diplomatic “gifts” to barbarian kings. You’re not just looking at a coin; you’re looking at a 1,500-year-old survival token from the man who tried to glue the Roman Empire back together.

And against all odds, it worked — for a while.

⚔️ A Coinage as Ambitious as Its Emperor

Justinian I Coins (527–565 AD) wasn’t your average emperor. He was obsessed with legacy, with restoring the Roman Empire, and with ensuring everyone knew who was boss — both in heaven and on earth. And like any good ruler, he understood the power of imagery.

So he minted coins that didn’t whisper. They shouted.

Justinian’s coinage proclaimed:

• “God & Emperor Are One” – No more pagan gods. The obverse featured Justinian dressed as a holy warrior. On the reverse? Angels, not Victories, and crosses instead of spears.

• “Rome Is Back” – Though the Eastern Empire spoke Greek, his coins were still inscribed in Latin, the sacred tongue of old Rome. It was a message to the world: this wasn’t just a continuation — it was a resurrection.

• “My Face, Everywhere” – From the mint at Constantinople to the workshops in Ravenna, Antioch, and Carthage, Justinian’s face was the brand. He was the emperor, the priest, the general — and his image backed every coin.

Try flipping a bronze follis under the sun. That big “M”? It means 40 nummi — but it also symbolizes a grand experiment in state economics: one denomination for everyone, including peasants and monks. Inflation? They tried to fight it. Sometimes it worked.

💰 Gold That Built an Empire

Let’s start with the star of the show.

The Solidus (≈ 4.5 grams of near-pure gold)

These were the hard currency of Byzantium. For over 700 years, the solidus remained largely unchanged — a testament to how well Justinian’s reforms held.

Obverse: Justinian, helmeted, armored, holding a globus cruciger (a globe with a cross on top — symbol of Christian dominion). He’s not just a ruler. He’s God’s representative on earth.

Reverse: An angel — sometimes serene, sometimes stern — standing with a cross or staff. Below her feet: “Victoria” (Victory), but you’ll notice it’s Christianized now. No wings, no pagans.

These coins weren’t just for local use. They traveled across Europe and the Middle East, traded by Arabs, hoarded by Slavs, and even admired by the Vikings, who used them as hacksilver. That’s how much trust they commanded.

🪙 Bronze: The Workhorse of the Empire

While gold funded wars and alliances, bronze coins paid for bread, bribes, and bathhouse entry. And here’s where it gets gritty — these coins were practical, overstruck, reissued, and often battered.

The Big Bronze Boys

• Follis (40 nummi) – Think of it as the ancient silver dollar (without the silver). Usually features Justinian’s bust and that big “M” on the reverse.

• Half Follis (20 nummi) – Same concept, half the value.

• Decanummium (10 nummi) – Everyday stuff. Buy bread, maybe a cup of garum (fermented fish sauce).

• Pentanummium (5 nummi) – The ancient equivalent of change you’d forget in your tunic.

Many of these coins were overstruck on earlier emperors’ bronzes — sometimes leaving ghostly images beneath. Why mint new blanks when you can recycle imperial PR?

🏛 Mints That Made History

Justinian’s coinage came from across the empire — but each mint had its own character. Here’s a cheat sheet:

Each mint left clues — subtle variations in style, spacing, and strike strength. A trained eye can sometimes guess the mint just by design elements alone.

🧠 Why Collectors Go Wild for Justinian Coins

Let’s be honest — these aren’t just coins. They’re tiny capsules of imperial ambition. Here’s why people hunt them:

1. Power in Your Pocket

A solidus is more than a collectible. It’s a piece of imperial propaganda, made from gold that once paid for cathedrals and campaigns.

2. Variety

You’ve got gold solidi and tremisses (⅓ solidus) — perfect for bishops and bribes. Then you’ve got bronze in all sizes, from massive folles to tiny pentanummia. Some coins even feature Justinian and Christ side by side — bold move for the 6th century.

3. Historical “Easter Eggs”

Find a follis with a test cut? Someone bit that coin in 540 AD to make sure it was real. Find one with a clear regnal year like “XX”? That means it was minted in Justinian’s 20th year on the throne — and survived two decades of war and plague.

4. Affordability (Yes, Really)

You don’t have to be a museum to collect Byzantine coins. Bronze folles can be found for under $100. Even a worn solidus can be yours for under $1,000 — and that’s a real gold coin from a real emperor.

🕊 A Legacy That Outlasted Justinian Himself

Even after Justinian died, his coins lived on — literally. The design of his solidus became the template for gold coinage across the Mediterranean:

• Islamic caliphs used his coin design before striking their own

• Crusaders hoarded his gold centuries later

• Byzantine mints kept copying his style long after his reign

• Modern numismatics uses Justinian coins as reference points for dating and regional coin studies

His dream of Renovatio Imperii (restoring the Roman Empire) didn’t last forever, but his coins? They’re still here. Still shining. Still speaking.
