Market values current as of March 2026The World of Ancient Roman Coins
Ancient Roman coins are tangible connections to one of history's greatest civilizations. Spanning roughly eight centuries, Roman coinage documented emperors, gods, victories, buildings, and political propaganda with remarkable artistry. Today, these coins are among the most actively collected ancient artifacts — and unlike many antiquities, they remain legally collectible and widely available at all price levels.
The Roman coin market is mature and well-served by specialist dealers, auction houses, and an extensive body of reference literature. Whether you have found a single Roman coin or inherited a collection, this guide will help you understand what you have and what it might be worth.
Roman Coin Denominations

Republican Coinage
Roman Republican coins (c.211 BC-27 BC) predate the emperors and feature different designs: the goddess Roma, the Dioscuri (Castor and Pollux), and later the portraits and symbols of competing political leaders like Julius Caesar, Brutus, and Mark Antony. The famous "EID MAR" denarius of Brutus, commemorating the assassination of Caesar, is among the most valuable ancient coins — an example sold for over $4 million in 2020.
Republican denarii are collected by Crawford number (from Michael Crawford's standard reference "Roman Republican Coinage"). Common types are available for $75-200, while rare types and high-grade examples command thousands or tens of thousands.
Imperial Portraits: Reading the Story
Every Roman imperial coin tells a story through its portrait and inscriptions. The obverse shows the emperor (or empress, or member of the imperial family) with a Latin inscription giving their names and titles. Learning to read these abbreviated legends is the key to identification.
Common Title Abbreviations
- IMP — Imperator (military commander/emperor)
- CAES — Caesar (imperial title)
- AVG — Augustus (supreme imperial title)
- P M — Pontifex Maximus (chief priest)
- TR P — Tribunicia Potestas (tribunician power — renewed annually, helps date coins)
- COS — Consul (followed by number, e.g., COS III = third consulship)
- P P — Pater Patriae (Father of the Country)
The style of portraiture evolved dramatically over the centuries. Early imperial portraits (Augustus, Tiberius, Nero) are realistic and refined. Second-century portraits (Hadrian, Marcus Aurelius) show mature classical style. Third-century portraits become rougher and more military. Fourth-century portraits are increasingly stylized and abstract, with large eyes and geometric features.
Collecting Strategies
The Twelve Caesars
One of the most popular collecting goals is assembling coins of the Twelve Caesars — the first twelve rulers from Julius Caesar through Domitian, as chronicled by Suetonius. This set spans a price range from very affordable (Vespasian denarii from $75) to extremely expensive (Julius Caesar and Augustus portrait coins from $1,000+, and rare types from $10,000+).
Building by Theme
Many collectors focus on themes: architecture (coins showing temples, the Colosseum, harbors), animals, military campaigns, specific provinces, or particular emperors. Thematic collecting allows deep expertise and the satisfaction of building a coherent, meaningful collection regardless of budget.
Provincial Coins
Roman Provincial coins were minted throughout the empire by local authorities, often featuring local temples, landmarks, and deities alongside the imperial portrait. This is a growing collecting area that offers excellent value — interesting provincial coins are often available at a fraction of the price of equivalent Roman mint issues.
The Market for Roman Coins
The ancient coin market is served by specialist auction houses including Classical Numismatic Group (CNG), Heritage Auctions (ancient department), Roma Numismatics, and numerous European houses. Major coin shows (NYINC, Long Beach, Munich) provide opportunities to buy from dealers and build relationships.
Prices for common types have been relatively stable, while rare and exceptional pieces continue to set records. The market for high-grade Roman gold has been particularly strong, driven by collectors seeking portable stores of value with historical significance.
Provenance matters increasingly in the ancient coin market. Documented ownership history (ex-collection references, old dealer tickets, auction catalog appearances) adds confidence about authenticity and legal status. Always prefer coins with traceable histories.

How to Value This Item: Step by Step
-
Identify the Metal and Denomination
Determine whether the coin is gold (aureus/solidus), silver (denarius/antoninianus/siliqua), or bronze/copper (sestertius, dupondius, as, follis). The metal immediately narrows the denomination and date range. Weight helps confirm: a denarius weighs ~3.5g, a sestertius ~25g, an aureus ~7.5g.
-
Read the Obverse Legend
The obverse inscription identifies the emperor (or empress, or Roman Republic issue). Decipher the abbreviated Latin titles: IMP (Imperator), CAES (Caesar), AVG (Augustus), PM (Pontifex Maximus), TR P (Tribunicia Potestas), COS (Consul). These titles help identify and date the coin.
-
Examine the Reverse Design
The reverse typically shows a deity, personification, building, military scene, or commemorative design with its own legend. The reverse type helps identify the specific issue and date. Many reverses carry propaganda messages — Victory, Libertas, Concordia, etc.
-
Determine the Specific Issue
Using the obverse portrait/legend and reverse type, look up the coin in standard references: RIC (Roman Imperial Coinage) for imperial coins, Crawford (Roman Republican Coinage) for Republic issues. Online databases like Wildwinds and NumisWiki are free starting points.
-
Assess the Condition
Grade the coin: Fine (clear portrait, most legend readable), VF (sharper detail, complete legend), EF (minimal wear, sharp detail), and AU/Mint State (essentially no wear). For ancient coins, centering, strike quality, and surface condition (corrosion, scratches, deposits) also affect grade.
-
Research Market Value
Check recent auction results on CNG, Heritage, Roma Numismatics, and ACSearch.info for comparable coins. Ancient coin pricing is less standardized than modern coins, making auction records essential. Condition, rarity, historical significance, and eye appeal all affect realized prices.
What Drives the Value
- Metal — gold aurei/solidi command the highest prices, followed by silver, then bronze/copper
- Emperor rarity — coins of short-reigning or obscure emperors are scarcer and often more valuable
- Historical significance — coins commemorating major events (conquest, triumph, death) attract premiums
- Condition — eye appeal matters hugely; a well-centered, sharply struck coin outperforms a poorly struck higher-grade piece
- Portrait quality — expressive, well-executed portraits are highly prized by collectors
- Reverse type rarity — some reverse designs are much rarer than others for the same emperor
- Provenance — coins from named collections or with documented find histories are increasingly valued
Identification Checklist
- Roman coins were struck (hammered between dies), not cast — genuine coins show flow lines and die polish marks under magnification
- The portrait style helps date coins even if the legend is illegible — early Empire portraiture is realistic, 3rd century is rougher, 4th century is stylized
- Silver denarii were debased over time: Republic/early Empire (~95% silver), Severan era (~50%), 3rd century crisis (silver-washed bronze)
- Sestertii (large bronze coins) were the "billboard" of Roman currency — their large size allowed detailed portraiture and complex reverse designs
- Provincial coins (minted outside Rome) often feature local landmarks, temples, and deities — they are a separate and growing collecting field
- The abbreviation "SC" (Senatus Consulto, "by decree of the Senate") appears on most bronze denominations of the early Empire
- Late Roman bronzes (4th-5th century) are the most affordable entry point — common types are available from $20-50 in decent condition
How to Spot a Fake
- Cast forgeries show a porous, sandy surface texture versus the smooth, flow-lined surface of struck genuine coins
- Check the weight against published standards — genuine coins are consistent within their type
- Edge examination: struck coins have irregular, slightly raised edges; cast copies show a seam line or filed edge
- Look for die flaws — genuine dies develop cracks and wear that transfer to coins; each die produces a consistent pattern
- Tooled or enhanced coins — some genuine but worn coins are "tooled" (details re-engraved) to appear higher grade; this reduces value dramatically
- Silvering on late Roman bronzes should be uneven and partially worn; uniform silvering may indicate modern plating
