What Does Attribute Mean?

To attribute a coin means to identify and describe it as accurately as possible using its physical characteristics, inscriptions, and published references.

The goal isn't just to name the ruler. It is to understand exactly what the coin is.

Identify the Portrait

The portrait is often your first clue. Ask yourself a few quick questions.

Even heavily worn portraits often narrow the possibilities considerably.

Read Whatever You Can

Don't worry if you can't read the entire inscription. Many experienced collectors can't either. Ancient inscriptions often contain abbreviations, ligatures, and worn letters that make complete readings impossible.

Instead, look for individual letters or recognizable words. Even a few surviving letters can dramatically narrow the possibilities. For Roman coins, the emperor's name is often the best clue. For Greek coins, city names, magistrates, or ethnic inscriptions can be equally important.

Study the Reverse

The reverse often identifies the specific coin type. Ask what you're actually looking at.

Small details can separate one variety from another.

Measure the Coin

Weight and diameter matter. In fact, weight is often more useful than diameter because many ancient coins were struck on irregular flans. Measurements help narrow the denomination and sometimes even the mint or period.

Determine the Metal

Is the coin gold, silver, billon, bronze or another copper alloy, or electrum? The metal immediately eliminates many possibilities.

Look for Mintmarks and Symbols

Many ancient coins carry small marks that are easy to miss but rich in information.

On many Roman coins, the mintmark appears in the exergue, the area below the main reverse design. Don't overlook tiny letters in the fields or exergue. They can be among the most important clues on the coin.

Compare With References

Now it's time to compare your observations with published references. Useful printed references include RIC, RPC, HGC, and Sear. Helpful online resources include OCRE, RPC Online, and WildWinds.

Don't begin with the books. Begin with the coin. Use the references to confirm your conclusions, not to guess blindly.

Confirm the Attribution

Once you think you've identified the coin, compare the portrait style, legends, reverse design, weight, diameter, mintmarks, and reference descriptions. Everything should agree.

If something doesn't match, keep looking. Experienced collectors often revise their first attribution after discovering a better match. In especially difficult cases, specialists may compare die matches with published examples to help confirm an attribution.

Can Every Coin Be Attributed?

No. Some coins are too worn, too corroded, or too incomplete to identify with certainty. Even museums sometimes label coins as uncertain ruler, uncertain mint, or uncertain denomination.

Learning when an attribution is uncertain is just as important as identifying a coin correctly.

A Simple Example

Imagine you have an unidentified silver coin. You notice a laureate male portrait, a weight of approximately 3.2 grams, Victory standing on the reverse, and the letters "...IANVS..." in the obverse legend.

None of these clues alone identifies the coin. Together, however, they greatly narrow the possibilities. By comparing those observations with published references, you may determine the coin is a Roman silver denarius of Trajan.

That's exactly how attribution works. You gather clues first. Then you use references to confirm your conclusion.

Common Mistakes

Beginning collectors often fall into a few familiar traps.

The best attributions come from considering all of the evidence together.

Why Attribution Matters

Learning attribution changes the way you collect. Instead of seeing an old Roman coin, you begin to recognize a coin struck by a particular ruler, at a specific mint, during a specific moment in history.

Every correctly attributed coin tells a richer story. It's one of the most satisfying skills a collector can develop.

My Advice to New Collectors

Don't be intimidated by attribution. No one starts as an expert. Every experienced numismatist began by comparing portraits, reading partial legends, and slowly learning how to connect the clues. The more coins you study, the more patterns you'll recognize.

Eventually, you'll stop asking "what is this coin?"

Instead, you'll ask: what do all of these clues tell me? That's the moment you've started thinking like a numismatist.

History wasn't just written. It was minted.
