How to Read Roman Coins: Decoding the Language of an Empire
At First Glance a Roman Coin Looks Like a Circle of Random Letters. Learn a Few Patterns, and It Begins to Speak.
One of the most intimidating parts of ancient coin collecting is the lettering. At first glance, a Roman coin can look like a circle of random letters. IMP. AVG. P P. TR P. COS. What does any of it mean?
The good news is that you don't have to memorize hundreds of abbreviations. Once you understand a few common patterns, Roman coins become surprisingly readable.
Learning to decode these legends is one of the biggest steps from simply owning an ancient coin to truly understanding it.
Roman Coins Tell a Story
Unlike many modern coins, Roman coins weren't designed simply to show a ruler's portrait. They also communicated the emperor's titles, honors, authority, and political message.
The legends were an important part of that message. Every abbreviation had a purpose.
Start With the Portrait
The portrait tells you whose coin you're holding. Even if you can't read every letter, recognizing the portrait gives you a place to start. Remember that not every Roman coin depicts an emperor. Many feature empresses, Caesars, heirs to the throne, or other members of the imperial family.
Once you've identified the portrait, begin reading the surrounding legend. Most Roman legends are intended to be read clockwise, although worn or off-center coins can make this difficult. Don't worry if some letters are missing. Experienced collectors identify coins from incomplete legends every day.
Don't Try to Read Every Letter
This is the biggest mistake beginners make. Roman legends use abbreviations extensively. Instead of writing long titles in full, Roman mints shortened them. Once you recognize the common abbreviations, reading coins becomes much easier.
If you ever need help, the Kinzer Coins Roman Coin Legend Translator is a great place to start. Rather than memorizing every title, you can quickly decode unfamiliar abbreviations while learning how Roman legends were constructed.
Common Roman Abbreviations
Here are some of the abbreviations you'll encounter most often.
- IMP Imperator, commander or emperor
- CAES Caesar
- AVG Augustus
- DN Dominus Noster, Our Lord, common on later coins
- P M Pontifex Maximus, Chief Priest
- TR P Tribunicia Potestas, Tribunician Power
- COS Consul
- P P Pater Patriae, Father of the Fatherland
These titles often changed during an emperor's reign, which means they can sometimes help date a coin.
The Reverse Matters Too
Many beginners focus only on the portrait. The reverse often tells just as much of the story.
- Gods and goddesses
- Military victories
- Personifications such as Victory, Peace, Justice, or Fortune
- Buildings
- Animals
- Commemorative events
The reverse legend usually explains the message being presented. Phrases such as FEL TEMP REPARATIO, GLORIA EXERCITVS, and VICTORIA AVGG were carefully chosen to communicate imperial achievements, military success, or political ideals.
Mint Marks and Officina Marks
Many later Roman coins include mint marks. These usually appear in the exergue, the area below the main reverse design. Examples include SMN, ANT, CON, and ROM.
Many coins also include letters or symbols identifying the workshop, known as the officina, within the mint. Learning these marks opens another fascinating layer of the coin's history.
You Don't Have to Learn Latin
Many new collectors assume they need to learn Latin before they can understand Roman coins. The good news is, you don't. Most experienced collectors recognize recurring abbreviations rather than translating every inscription word for word.
As your collection grows, you'll naturally become familiar with titles like IMP, AVG, and COS. If you encounter a legend you don't recognize, simply use the Kinzer Coins Roman Coin Legend Translator. The goal isn't to memorize every inscription. It is to become comfortable recognizing the patterns.
