Quick answers

Late Western Roman Coin Values, Explained Clearly

Book III is designed to answer practical collector questions such as “What is a Romulus Augustulus coin worth?”, “What is a Valentinian III coin worth?”, and “Why do prices become so specimen-specific near the end of the Western Roman Empire?”

What period does Book III cover?
AD 364–476, from Valentinian I through Romulus Augustulus. Julius Nepos remains part of the historical afterword through AD 480.
How are values compared?
Certified/slabbed market first, fixed-price raw retail second, and buyer-inclusive raw auction acquisition cost third.
Why do some rulers have no normal range?
For Specialist Only rulers, a manufactured range would create false precision. Exact comparable transactions are more useful.
How current is the research?
Book III uses a September 20, 2026 research cutoff and a current-retail snapshot from the same period.
How the guide works

Market evidence in a fixed order

Book III preserves the methodology established in Books I and II while adding stricter controls for market confidence, repeat specimens, issuing authority, and compromised late-western material.

1. Certified / slabbed market first
Certified material is treated as its own market and compared grade-for-grade where the evidence supports it.
2. Fixed-price retail second
Current asking prices show what a collector can actually buy now without waiting for an auction.
3. Buyer-inclusive raw auction third
Auction acquisition cost uses hammer plus the exact mandatory premium for that sale. No blanket premium is applied.
4. Market confidence is explicit
Established, Limited, Thin, and Specialist Only labels tell the reader how much pricing precision the evidence supports.
5. Same-specimen sales are linked
Repeated auction appearances of one rare coin are not counted as multiple population members.
6. Authority and condition come first
Official, Ricimer-associated, pseudo-imperial, clipped, cracked, tooled, and otherwise compromised material is separated before valuation.

Late Roman Coin Types & Value Questions

Book III spans the point where broad imperial coinage gives way to much thinner late-western markets. Denomination, mint, issuing authority, condition, and provenance become progressively more important.

AE2 / AE3 / AE4 bronze values
Accessible late Roman bronze of Valentinian I, Valens, Gratian, Theodosius I, Honorius, Valentinian III and others.
Siliqua values
Silver markets for rulers from Valentinian I through Constantine III, Jovinus, Priscus Attalus and other scarce western emperors.
Tremissis values
Gold fractions become increasingly important after AD 455, including Avitus, Majorian, Johannes, Glycerius, Julius Nepos and Romulus Augustulus.
Solidus values
Commoner fourth-century gold gives way to specialist and trophy-level late-western issues where exact specimen history matters.
Official vs. pseudo-imperial values
Majorian, Libius Severus and related issues require authority classification before any price comparison is meaningful.
Ultra-rare final western emperors
Olybrius, Glycerius, Julius Nepos and Romulus Augustulus often belong to exact-comparable markets rather than conventional price ladders.

Research notes

How Book III Was Researched

Prepared by Kinzer Coins as a dated collector-market reference. Book III separates evidence classes, preserves thin and specialist-only markets, and tracks specimen identity where repeated auction appearances could otherwise distort the market.

Certified market
Grade-specific slabbed observations are treated separately from raw coins.
Current dealer retail
Active fixed-price asking prices are used to show what collectors can buy now.
Buyer-inclusive auctions
Hammer plus the mandatory premium for each exact sale; no universal premium is applied.
Historical currency conversion
Foreign results retain original currency and use historical FX only when a common-currency comparison is needed.
Repeat-sale control
Weight, flan shape, dies, marks, provenance and prior images are used to recognize the same physical coin.
Specialist-market discipline
No median is better than a misleading median when a ruler is represented by only a handful of meaningful comparables.

Market evidence is a dated snapshot, not a guarantee of future value. Ancient coins remain specimen-specific.

Questions collectors ask

Book III FAQ

What is a Romulus Augustulus coin worth?
There is no ordinary range. Recent exact comparables include a Milan tremissis at $65,000 hammer, a certified Choice XF tremissis at $66,000 sold-for, Milan solidi at CHF 85,000 and CHF 190,000, and a Rome solidus at £95,000.
What is a Valentinian III coin worth?
His market is much broader. Bronze can remain accessible, while a recent four-coin certified solidus sample produced a $2,340 buyer-inclusive median.
Why do some Book III rulers have no price range?
When the market is too rare or specimen-specific, exact comparables are more accurate than a synthetic minimum-to-maximum range.
Why are certified coins shown separately?
Certification narrows comparison by grade and attribution. Raw and slabbed coins therefore remain separate evidence classes.
Why does issuing authority matter in late western coins?
Official imperial, Ricimer-associated, attribution-sensitive and pseudo-imperial pieces can carry very different markets even when they bear the same ruler’s name.
How are auction values calculated?
Buyer-inclusive acquisition cost uses hammer plus the mandatory buyer premium for that exact sale. No blanket percentage is applied across auction houses.
