How to Start Collecting Ancient Roman Coins: A Beginner's Complete Guide

Want to start collecting ancient Roman coins? You do not need to memorize every emperor, read Latin fluently, or spend thousands of dollars. A good first collection begins with a trustworthy seller, a basic understanding of attribution, and one genuine coin tied to history you already care about.

This guide covers the essentials without trying to turn your first purchase into a graduate course in Roman numismatics.

1. Decide What Interests You About Rome

Do not start by asking which coin is the “best investment.” Start with the history.

You might be interested in Julius Caesar and the fall of the Republic, Augustus and the first emperors, the Five Good Emperors, the Crisis of the Third Century, Constantine and Christianity, Roman Britain, military history, or the final centuries of the Western Empire.

A coin connected with a subject you already enjoy gives you a reason to research it after the purchase.

2. Learn the Main Roman Coin Periods

Roman coinage spans many centuries, and the monetary system changed repeatedly.

Roman Republic

Republican coins include early cast bronze, struck silver, and the denarius system introduced around 211 BC. Later Republican denarii became increasingly rich in family, religious, military, and political imagery.

Early and High Roman Empire

From Augustus onward, imperial portraits became central to Roman coinage. Denarii, aurei, sestertii, dupondii, asses, and other denominations offer a huge range of rulers and historical types.

Third Century

The antoninianus became increasingly important while repeated debasement, civil wars, invasions, and monetary reforms transformed Roman coinage.

Late Roman Empire

Diocletian, Constantine, and later emperors repeatedly reformed the currency. Collectors often use modern size labels such as AE1, AE2, AE3, and AE4 because the ancient names of many later bronze denominations are uncertain.

3. Learn a Few Denominations

Denarius: the great Roman silver denomination introduced during the Republic and used for centuries.

Sestertius: best known to collectors as the large imperial copper-alloy denomination with broad portraits and reverses.

Antoninianus: introduced under Caracalla in AD 215 and later heavily debased during the third century.

Late Roman bronze: an accessible category that includes many fourth- and fifth-century coins. AE1–AE4 are modern size classifications rather than ancient denomination names.

Aureus and solidus: important Roman gold denominations from different periods and generally more expensive entry points.

4. Choose a Beginner-Friendly Ruler

There is no single correct first emperor, but some rulers combine strong history with abundant surviving coinage.

Constantine I is one of the easiest recommendations. His bronze coins are widely available, historically important, and excellent for learning mint marks and reverse types.

Gordian III is a popular route into third-century silver because many antoniniani survive.

Probus offers extraordinary bust, mint, and reverse variety.

Trajan, Hadrian, Antoninus Pius, Marcus Aurelius, and Vespasian connect collectors with famous periods of the empire, although attractive silver or large bronze examples may cost more than common Late Roman bronzes.

Why we recommend Constantine the Great as a first ancient coin.

5. Learn How to Read a Roman Coin

Obverse: usually carries a portrait and legend naming the emperor, empress, Caesar, or other authority.

Reverse: can show a deity, personification, military scene, building, animal, victory, imperial family member, province, or political message.

Legend: abbreviations such as IMP, CAES, AVG, TR P, COS, and P P help identify titles and sometimes narrow the date.

Exergue: the space beneath the main reverse design. On many Late Roman coins it contains a mint signature and workshop information.

You do not need to translate everything immediately. Start with ruler + reverse + mint.

6. Understand Raw vs. Certified Ancient Coins

Both are legitimate ways to collect.

A raw coin is not encapsulated and can be handled directly. This is the traditional format for much of the ancient-coin market.

A certified or slabbed coin has been encapsulated by a third-party grading service and normally includes an attribution and grade opinion.

NGC Ancients states that it will only grade ancient coins it believes to be genuine, but its ancient-coin authenticity and attribution determinations are expert opinions rather than the same guarantee structure used for many modern coins. A reputable seller’s authenticity policy therefore remains important whether the coin is raw or slabbed.

7. Know What Determines Price

Ancient coins do not have one universal price guide. Value can change dramatically based on:

• Ruler or issuing authority
• Denomination
• Mint and date
• Reverse type
• Rarity
• Portrait style
• Strike and centering
• Wear
• Patina and surfaces
• Tooling, smoothing, or restoration
• Provenance
• Current collector demand

Compare recent sales of genuinely similar coins rather than relying on a fixed dollar range from an old article.

8. Buy From a Reputable Source

For a beginner, seller quality matters more than hunting for the lowest possible price.

Look for established ancient-coin dealers and auction houses that provide accurate descriptions, clear photographs, return terms, and meaningful authenticity policies.

Be especially cautious with unidentified marketplace listings, implausibly cheap rarities, vague provenance claims, and sellers offering large numbers of suspiciously similar “ancient” coins.

At Kinzer Coins, every ancient coin we sell is covered by our lifetime authenticity guarantee. That guarantee is ours and is separate from any third-party grading service.

9. Pick a Simple First Collection

One Ruler

Choose Constantine I, Probus, Gordian III, or another ruler and collect different reverses, mints, denominations, or portrait styles.

One Dynasty

Build the Julio-Claudians, Flavians, Antonines, Severans, Constantinians, or another imperial family.

One Historical Theme

Collect military reverses, Roman gods, Christian symbols, provincial cities, architecture, emperors of the third-century crisis, or coins connected with a war or historical period.

10. Attribute Your First Coin Yourself

Even if the seller provides a complete attribution, try to verify it.

Identify the ruler from the legend, describe the reverse, find the mint mark if present, note the weight and diameter, and compare the coin with reputable references.

That process is where collecting becomes more than buying.

Frequently Asked Questions

How much money do I need to start collecting Roman coins?

You can begin with modestly priced Late Roman bronzes rather than expensive silver or gold. There is no fixed minimum budget; authenticity, attribution, and historical interest matter more than spending a particular amount.

What is the best first Roman coin?

A common, clearly attributable bronze of Constantine I or another well-documented fourth-century ruler is an excellent first choice. The best coin is one you understand and genuinely want to research.

Are ancient Roman coins legal to own?

Ancient coins are legally collected in many countries, but ownership, export, import, and cultural-property rules vary. Buy from reputable sources, preserve provenance and invoices, and follow the laws that apply to your jurisdiction.

Should I clean my first Roman coin?

Do not aggressively clean an attributed collectible coin. Improper cleaning can permanently damage surfaces and reduce value. Uncleaned ancient coins are a separate specialty that requires patience and appropriate conservation techniques.

How do I know a Roman coin is real?

No single visual test proves authenticity. Style, metal, weight, fabric, surfaces, dies, strike, provenance, and comparison with genuine examples all matter. For beginners, buying from a reputable specialist with a strong authenticity policy is the simplest protection.

Your First Coin

The best first ancient Roman coin is not necessarily the cheapest, rarest, or highest graded. It is a genuine coin you understand, from a source you trust, tied to a story that makes you want to learn what comes next.

Start with one. Learn the portrait, legend, reverse, mint, and historical context. Once that coin stops feeling mysterious, the entire Roman series becomes easier to explore.
