SECTION 1 β€” WHAT ARE BYZANTINE COINS?

Definition, terminology, and historical context

Definition & Historical Context

Byzantine coins are the currency of the Eastern Roman Empire from approximately AD 491 to 1453, spanning from the reign of Anastasius I to the fall of Constantinople. These coins represent the direct continuation of Roman imperial coinage, transformed by Christian theology and Greek culture.

Continuity from Rome

Byzantine coinage is not a break from Rome but an evolution. The solidus maintained Roman weight standards, imperial portraits continued, and Latin initially remained the language of legends. The transition was gradual over centuries.

Why "Byzantine" is a Modern Term

The term "Byzantine Empire" was coined by 16th-century historians. Contemporaries called themselves Rhomaioi (Romans) and their state the Basileia Rhomaion (Roman Empire). "Byzantine" distinguishes the medieval Eastern Roman Empire from classical Rome.

Distinctive Byzantine Characteristics

Christian Imagery

Christ Pantocrator, Virgin Mary, crosses, and saints replace pagan gods

Greek Language

Transition from Latin to Greek inscriptions (7th–8th centuries)

Frontal Portraits

Emperors face forward, emphasizing divine authority rather than classical realism

Stable Gold

Solidus maintained 24-carat purity for 700 years – medieval world's dollar

🟣

SECTION 2 β€” TRANSITION FROM ROMAN TO BYZANTINE

Anastasius reforms and the creation of Byzantine coinage

The Anastasian Monetary Reform (498 AD)

Emperor Anastasius I's reforms marked the definitive break from Late Roman coinage and established the Byzantine system that would last for centuries.

The Follis System

Bronze Denominations: Anastasius introduced a standardized bronze coinage with clear markings:

Follis (40 nummi) M Mark of value = 40
Half-Follis (20 nummi) K Mark of value = 20
Decanummium (10 nummi) I Mark of value = 10
Pentannummium (5 nummi) Π„ Mark of value = 5

These large bronze coins (27–40mm) were easily identifiable by their Greek numeral markings, solving the confusion of Late Roman bronze coinage.

Language Transition

Latin to Greek Shift: The gradual linguistic transition reflected broader cultural changes:

Early (5th–6th C)

Latin dominant: DN (Dominus Noster), PF (Pius Felix)
Example: D N ANASTASIVS P P AVG

Transition (7th–8th C)

Mixed usage: Greek appears alongside Latin
Example: DN CONSTANTINVS PP AV

Byzantine (9th C+)

Greek dominant: ΒΑΣΙΛΕΞ₯Ξ£ Ξ‘Ξ©ΞœΞ‘Ξ™Ξ©Ξ (King of the Romans)
Example: +ΙωΑΝΝΗБ ΒΑБΙΛЄΞ₯Π‘

Elements of Continuity

Gold Standard

The solidus (4.5g of pure gold) continued unchanged from Constantine's reform of 309 AD

Imperial Image

Emperor's portrait remained central, though style shifted from profile to frontal

Mint System

Constantinople mint continued operations with similar organization

SECTION 9 β€” IDENTIFYING BYZANTINE COINS

Practical guide for attribution and dating

Step-by-Step Identification Process

1
Read the Legends

Early coins: Latin abbreviations (DN, PF, AVG)
Middle coins: Mixed Latin/Greek
Late coins: Greek (ΒΑΣΙΛΕΞ₯Ξ£, Ξ”Ξ•Ξ£Ξ ΞŸΞ€Ξ—Ξ£)
Key: Emperor name is usually in genitive case

2
Distinguish Christ vs Emperor

Christ: IC-XC abbreviation, cross nimbus, beard
Emperor: Crown, regalia, sometimes labeled
Note: Some emperors imitated Christ's appearance

3
Analyze Fabric & Weight

Solidus: 4.5g gold, thin, well struck
Follis: Large bronze, Greek numerals
Trachy: Concave shape (11th–13th C)
Weight clues: Reduction indicates later period

4
Check Mint Marks

Constantinople: CON, CONOB (gold), Ξ˜Ξ•ΞšΞ’ (bronze)
Thessalonica: Ξ˜Ξ•Ξ˜, Ξ˜Ξ•ΞšΞŸΞ₯
Syracuse: SCL, SIRACVSA (early period only)
Position: Usually in exergue (bottom)

Common Identification Challenges

Worn Legends

Byzantine bronzes often have weak strikes. Use oblique lighting and magnification.

Anonymous Folles

No emperor names (970–1092). Identify by Christ type and classification system.

Late Empire Confusion

Poor quality, irregular issues. Focus on weight, module, and general style.

Imitations

Bulgarian, Islamic, Crusader imitations exist. Check weight, style, and legends.

SECTION 12 β€” COLLECTING BYZANTINE COINS

Practical guide for building a Byzantine collection

Beginner-Friendly Types

Anonymous Folles

10th–11th century bronzes with Christ types. Affordable ($20–$100), varied, and historically interesting.

Easy
Late Byzantine Bronze

13th–15th century small modules. Very affordable ($10–$50), though often poorly preserved.

Easy
12th Century Trachy

Concave billon coins. Distinctive shape, moderate prices ($50–$200). Attribution can be challenging.

Medium

Storage & Care Guidelines

Never Do
  • Never clean Byzantine bronzes – patina is protective
  • Never store in PVC flips or acidic materials
  • Never use rubber bands or adhesive labels directly on coins
  • Never expose to rapid temperature/humidity changes
Always Do
  • Use archival storage (Mylar flips, acid-free trays)
  • Handle carefully – Byzantine bronzes are often brittle
  • Document each coin with photos and details
  • Store in stable environment (50% RH, 70Β°F ideal)

Cleaning Rules for Byzantine Coins

Bronze Coins

Generally: Do not clean. Patina protects and adds value.
If necessary: Distilled water soak only. No chemicals.
Exception: Heavy crust may be professionally removed.

Gold & Silver

Gold solidus: Usually stable, gentle soap if dirty.
Silver: May have desirable toning. Minimal cleaning.
Always: Test small area first, be conservative.

Professional Help

When: Valuable coins, uncertain about condition.
Who: Professional numismatic conservators only.
Cost: Usually $50–$200 per coin depending on work needed.

Golden Rule: It's easier to clean more later than to undo damage from overcleaning.

SECTION 13 β€” LEGACY OF BYZANTINE COINAGE

Influence on medieval Europe, Islamic world, and beyond

Enduring Influence

Byzantine coinage didn't disappear in 1453β€”its influence persisted for centuries in the monetary systems of successor states and trading partners.

Medieval Europe

The solidus ("bezant") was the dollar of medieval trade. Venetian ducat and Florentine florin copied Byzantine weight standards. Crusader states issued Byzantine-style coins. Byzantine iconography influenced medieval Christian art.

Islamic Influence

Early Islamic coinage (Umayyad) copied Byzantine types with Arabic inscriptions. The gold dinar was based on solidus weight. Byzantine minting technology influenced Islamic coin production. Cross-cultural designs emerged in border regions.

Continuity of Roman Authority

Byzantine coins maintained the fiction of universal Roman Empire long after the West fell. They were diplomatic gifts demonstrating imperial prestige. The emperor's image asserted sovereignty over distant regions. Lasted until 1453β€”longest continuous coinage tradition.

Successor States & Continuations

Trebizond Empire

Issued Byzantine-style coins until 1461. Silver asper based on Byzantine types.

Morea Despotate

Palaiologos rulers issued coins in Byzantine tradition until Ottoman conquest.

Russian Claims

Moscow as "Third Rome" adopted Byzantine symbols and imperial claims.

Mount Athos

Monastic communities used Byzantine coins long after political empire ended.

The Byzantine Numismatic Legacy

Byzantine coins are more than historical artifactsβ€”they are tangible links to a civilization that preserved classical knowledge through the Middle Ages, transmitted Roman institutions to medieval Europe, and created distinctive Christian art that would influence Orthodox cultures for centuries.

"In their gold and bronze, we trace not just economic history, but the very idea of Christian empire that shaped medieval Europe and the Orthodox world."

Lasting Impact: 1000 years of continuous minting
Cultural Bridge: Classical Antiquity to Middle Ages
Artistic Tradition: Distinctive Christian iconography
Economic Standard: Bezant as medieval reserve currency
