What Is a Constantine Coin Worth?
What is a Constantine the Great coin worth? There is no single price. Common Late Roman bronzes of Constantine I can be very affordable, while scarcer mints, rare reverse types, exceptional portraits, strong surfaces, and high-grade examples can sell for much more.
The most important rule is simple: attribute the coin first, then compare prices. Two Constantine bronzes that look nearly identical to a beginner can have very different values.
Who Was Constantine the Great?
Constantine I ruled from AD 306 to 337. He is one of the most important emperors in Roman history because of his victory in the civil wars, his support for Christianity, and the foundation of Constantinople on the site of Byzantium.
His long reign produced a huge range of coins from many imperial mints, which is one reason Constantine is so popular with both beginners and specialists.
How Much Is a Constantine Coin Worth?
A reliable value depends on the exact coin. Important factors include the ruler, denomination or module, mint, officina, reverse type, legend, rarity, condition, centering, strike, patina, surfaces, alterations, provenance, and current collector demand.
Because the market changes and ancient coins vary so much individually, fixed price charts age quickly. Recent auction results and dealer listings for genuinely comparable coins are much more useful.
Why Are Some Constantine Coins Cheap?
Many fourth-century bronze issues were struck in enormous quantities and survive in large numbers. Common types in ordinary condition can therefore remain accessible even though they are nearly 1,700 years old.
Low price does not automatically mean low historical importance. A common Constantine bronze can still carry a portrait, mint mark, political message, military reverse, or religious symbolism that makes it an excellent first ancient coin.
Which Constantine Coins Are More Valuable?
Higher values tend to appear when several desirable factors come together. Examples can include:
- Scarcer mints or officina combinations
- Rare reverse types
- Unusual bust varieties
- Strong portraits and full legends
- Exceptional centering and strike
- Attractive, stable surfaces
- Well-established Christian significance
- Important provenance
- Rare posthumous or ceremonial issues
Rarity alone does not determine price. A rare coin with poor surfaces may sell for less than a common type with exceptional eye appeal.
Common Constantine Bronze Types
AE3 and AE4 Bronzes
Many Constantine-era bronzes are described today as AE3 or AE4. These are modern size classifications, not ancient denomination names.
Common examples are often good beginner coins because they can be inexpensive and still preserve useful attribution details such as legends and mint marks.
Learn how AE1–AE4 classifications work.
Campgate Coins
Campgate reverses are popular because they offer a strong collecting structure based on ruler, mint, officina, field marks, reverse legend, and architectural details.

Military Standard and Victory Types
Military standards, Victory figures, vows, and related reverses are common across Constantinian coinage. Their values depend on the exact issue rather than the broad theme alone.
Coins With Christian Significance
Constantine’s reign is closely connected with the rise of Christianity, but not every symbol on his coins is Christian. Traditional Roman imagery remained common, and Christian symbols became more visible gradually.
Coins with securely identified Christian symbolism can attract stronger demand, especially when the issue itself is scarce or historically important.
Lifetime vs. Posthumous Constantine Coins
Coins struck during Constantine’s lifetime and those issued after his death are both collectible. Some lifetime types are extremely common, while certain posthumous issues are scarce and highly desirable.
There is no simple rule that lifetime coins are always worth more. The exact type matters far more.
Does NGC Certification Increase Value?
Third-party encapsulation can add an independent attribution and grade opinion and may make some buyers more comfortable, especially beginners. Raw coins can be equally legitimate and collectible.
Certification by itself does not create rarity. The underlying coin—its type, condition, surfaces, style, and demand—still determines most of the value.

Yes. Common Constantinian bronzes are historically important, well studied, and often affordable, making them excellent coins for learning legends, mint marks, officinae, and Late Roman attribution.
How do I identify a Constantine coin before pricing it?

No. The Constantinian dynasty includes several rulers with similar names and titles, including Constantine II, Constantius II, and Constans. Accurate identification matters before estimating value.
