The Fascination with Ancient Roman Coinage

Numismatics—the study of coins, their history, and symbolism—is an essential window into ancient societies. During the reign of Emperor Hadrian (r. 117–138 CE), Roman coinage reached new heights of artistry, ideology, and historical importance. Collectors, scholars, and history enthusiasts alike find Hadrianic coins to be among the most compelling ancient numismatic treasures. 

1. Who Was Emperor Hadrian?

Publius Aelius Hadrianus, better known as Hadrian, ruled from 117 to 138 CE, succeeding Trajan. He is often remembered as one of the “Five Good Emperors.” Known for his intellectual pursuits—and famously for Hadrian’s Wall in Britain—he also took a keen interest in promoting Greek culture. His reign brought stability, consolidation, and cultural flowering. Understanding his priorities helps us interpret the coins minted under him.

2. The Role of Coinage in Hadrian’s Propaganda

2.1 Imperial Image & Titles

Hadrian’s coins often carry his portrait—an approachable yet powerful image, frequently with a laurel wreath or helmet. These visual elements promoted both his divinity and martial prowess. Inscriptions such as IMP CAESAR TRAIANVS HADRIANVS AVG (Emperor Caesar Trajan Hadrian Augustus) emphasized continuity from beloved predecessor Trajan and reinforced his legitimacy.

2.2 Ideological Messaging

Coins were the “mass media” of the Roman Empire. With widespread distribution, they conveyed messages of peace, prosperity, and stability. Hadrian used carefully selected imagery—like PAX AVGVSTI (Peace of the Emperor) or FELICITAS (Happiness)—to shape public perception and reinforce his policies.

3. Minting Practices & Coin Types

3.1 The Roman Minting System

During Hadrian’s reign, Rome operated multiple mints across the empire: Rome, Lyon, Antioch, Alexandria, and others. All struck gold (aureus), silver (denarius), and bronze (dupondius, sestertius, as, among others). Although the Roman mint system was centralized, regional mints had autonomy in certain design choices.

3.2 Gold Coin: The Aureus

  • Weight/Purity: Approximately 7.8 grams, high-purity gold.

  • Obverse: Bust of Hadrian—laureate, sometimes draped.

  • Reverse: Themes varied—emperors celebrating military triumphs, deities, or provincial personifications.

Example: Aureus with Deified Trajan

After Trajan’s death in 117 CE, Hadrian issued a gold aureus depicting deified Trajan (DIVI TRAIANI) on the reverse, often seated and holding a sceptre—highlighting dynastic continuity.

3.3 Silver Coin: The Denarius

  • Weight: ~3.4 grams.

  • Obverse: Emperor’s portrait, with inscriptions like HADRIANVS AVGVSTVS.

  • Reverse types:

    • Divinities: Jupiter, Mars, Venus, Hercules.

    • Abstract virtues: LIBERTAS, PRUDENTIA, FELICITAS.

    • Imperial events: Military victories, embassy receptions, investments in public works.

3.4 Bronze Coinage: As, Dupondius, Sestertius

  • Heavier and more numerous, these coins circulated widely in daily commerce.

  • Sestertii in particular showcased elaborate reverse designs: architectural motifs, commemorative scenes like the Tempietto at Tivoli—possibly linked to Hadrian’s Villa.

4. Iconographic Highlights & Symbolism

4.1 Genius of Rome (“Genius Populi Romani”)

A common motif: a youthful figure, draped, holding a cornucopia and patera—symbolizing the state’s spirit and abundance under Hadrianic rule.

4.2 Concordia & Public Harmony

Depicted through two figures clasping hands—one draped, one helmeted—signifying harmony between civilian and military realms.

4.3 Hadrian’s Greek Passion

Hadrian celebrated Greek culture and heritage. Some coins show him in Greek attire or revive Classical Greek styles, bridging the two cultures. An example is the portrayal of Athena or Apollo, often in a more Hellenized fashion.

4.4 Provincial Personifications

Coins minted in the East—Antioch, Alexandria, Tyre—feature regional personifications like Syria (leaning on an altar) or Alexandria (seated). These conveyed loyalty to Rome and Hadrian’s respect for Greek city traditions.

5. Mint Marks, Atelier Style & Chronology

5.1 Mint Marks and Control

Mint marks—tiny letters or symbols (e.g., SC = Senatus Consulto)—informed modern scholars about authority structures and duties.

5.2 Artist Signatures

Some Hadrianic coins bear engraver signatures—Aeternitas, Hermogenes—highlighting artistic pride and quality standards in die production.

5.3 Dating Coin Issues

Scholars categorize Hadrian’s coinage into:

  1. Early years (117–122 CE): Focus on Trajanic continuity, deified predecessor portraits.

  2. Middle phase (122–130 CE): Classical revival and Greek iconography.

  3. Late reign (130–138 CE): Return to imperial propaganda: peaceful empire, Roman stability, virtues.

6. Specific Numismatic Examples

6.1 Denarius: Hadrian & SPQR Felicitas

  • Obverse: Head of Hadrian, laureate.

  • Reverse: Standing figure of Felicitas holding caduceus—emphasizing Hadrian’s ability to bestow happiness.

6.2 Sestertius: Hadrian & Temple of Antoninus Pius

Toward the end of his reign, he issued sestertii featuring the deified Antoninus Pius on the reverse. This coin blended filial piety, public memory, and dynastic continuity.

6.3 Provincial Coin: Hadrian, Æ Bronze from Macedonia

Local issues sometimes depict Hadrian with Greek titles and inscriptions—like “ΑΥΤΟΚΡΑΤΩΡ ΗΔΡΙΑΝΟΣ”—demonstrating a synergy between Roman authority and local identity.

7. Coin Circulation & Economic Context

7.1 Circulation Patterns

Gold and silver coins circulated widely in imperial and military centers. Bronze coinage primarily served local markets, pay for soldiers, and grain distributions. Mint output and metallurgical consistency influenced inflation and commerce.

7.2 Debasement & Gold-Silver Ratio

Unlike other periods, Hadrian maintained fiscal conservatism—ensuring coin purity remained high, bolstering market confidence.

7.3 Toll Road Fees & Taxation

Coins were essential in collecting taxes and funding public works—Hadrian’s famous building programs (walls, baths, and temples) relied heavily on reliable coin supply.

8. Modern Numismatic Significance

8.1 Rarity and Condition

Hadrianic coins vary in rarity. Some provincial issues are scarce, while Roman-minted denarii and sestertii can be found in fine to extremely fine condition. The Morgan Library in the U.S. and the Vatican Museums hold exceptional collections.

8.2 Collectors’ Perspective

Collectors prize:

  • Artistic quality: Fine engravings and portraiture.

  • Historical value: Icons of Greek‐Roman policies.

  • Provenance: Coins with excavation histories (e.g., Ostia, Hadrian’s Villa).

8.3 Pricing & Market Factors

• Common sestertii: €100–300 (moderate grade)
• Fine denarii: €150–450
• Rare provincial bronzes: €500–1,500+
• Gold aurei: Often over €5,000 depending on type and condition

Values fluctuate based on:

  1. State of preservation

  2. Rarity of mint type

  3. Historical importance

  4. Certification by vetting bodies (e.g. NGC Ancients)

9. Preservation & Authentication

9.1 Detecting Forgeries

Modern forgeries exist. Look out for:

  • Tooling marks (uneven die pressure)

  • Backscattered light spots

  • Non-standard metal alloys

Professional glossaries advise using spectrometry or verified third-party certification (e.g. Numismatic Guaranty Company).

9.2 Conservation Best Practices

  • Store coins in inert membranes—not PVC

  • Use acid-free cardboard flips or archival coin capsules

  • Maintain low-humidity environment (~40–45%)

  • Avoid ultrasonic or harsh chemical cleaning

10. Tips for Beginner Collectors

  1. Start with denarii or common sestertii—affordable and widespread

  2. Buy from reputable dealers with condition guarantees

  3. Learn key mint marks & die axes (for fine attribution)

  4. Join numismatic societies (e.g. American Numismatic Association, U.K.’s BNJ)

  5. Use reference guides like

    • RSC (Roman Silver Coinage)

    • BMC (British Museum Catalogues)

    • Online platforms like CoinArchives.com
