The Most Expensive Ancient Coins Ever Sold

What counts as a record

Before the list, the honest caveat. "Most expensive ancient coin" is a specific and slippery claim, and it is worth being clear about what these numbers actually measure. Every figure here is a publicly documented auction result, total price with the buyer's premium included, converted to US dollars at the time of sale. Private sales between collectors and dealers can run higher and almost never become public, so a "record" here means the record we can see, not necessarily the record that exists. Where a price is widely cited but the exact figure varies across sources, we have used the most conservative published total and flagged the range.

"Ancient" we treat in the standard numismatic sense: roughly seventh century BC through the end of the Western Roman Empire in the fifth century AD, extending into the early Byzantine and early Islamic worlds where the line is genuinely a question of taste. The Umayyad gold dinar at the end of the list sits on that boundary and we explain why we included it. Modern coins — the 1933 Double Eagle, the Brasher Doubloon, the various dollar rarities that headline the broader "most expensive coin" lists — are out of scope here. This is the ancient list.

The order below runs by sale price, highest first. Where two coins are close, the more recent sale ranks higher, because the headline number is the one a future seller is going to quote.

1. The Pantikapaion gold stater — about $6.0 million

A gold stater of Pantikapaion, the capital of the Bosporan Kingdom on what is now the Crimean peninsula, struck around 340–325 BC. About 9 grams of gold the size of a US quarter, with on the obverse a wide-eyed bearded satyr in three-quarter view and on the reverse a winged griffin biting a spear in its beak, standing on an ear of corn. It is one of the great miniature sculptures of the ancient world. The sale: roughly $6.0 million at Numismatica Ars Classica's auction in Zurich on 18–19 May 2023, against a pre-sale estimate well below that figure.

The provenance is part of the price. This stater was in the Hermitage collection in Saint Petersburg until 1934, when the Soviet government, needing foreign currency to fund the first Five-Year Plan, sold off duplicates from the museum's holdings — one of several large dispersals of Imperial Russian collections in the 1920s and 1930s. The 2023 coin is understood to be the only specimen of this exact issue in private hands; the other comparable Pantikapaion staters of this design sit in museums. That combination of artistic quality, museum pedigree, and effective uniqueness is what cleared $6 million in a room that knew exactly what it was looking at.

Pantikapaion gold staters had pushed seven figures already — a different example was the cover lot of the Prospero Collection sale in New York in January 2012, where it realised about $3.8 million and held the auction record for an ancient Greek coin until the Akragas dekadrachm overtook it a few months later. The 2023 sale roughly doubled that. The longer story of how Greek gold went from the first coins struck in Lydia through to the Black Sea workshops that engraved this satyr is the Greek coinage hub; the dynasty that paid for the coin is one corner of the wider Hellenistic world.

2. The Brutus EID MAR aureus — about $4.2 million (with an asterisk)

The most politically loaded coin in Roman numismatics. Struck by Marcus Junius Brutus in 43–42 BC after the assassination of Julius Caesar, the reverse names the date directly: EID·MAR, the Ides of March, flanked by two daggers and a freedman's pileus cap. The obverse carries Brutus's own portrait. The piece is the original political-violence-on-a-coin design and, by deliberate choice, an admission written in gold. Three gold examples are known. One is on long loan to the British Museum, one is in the Deutsche Bundesbank's collection, and the third — the one that came up at auction — sold at Roma Numismatics in London on 29 October 2020 for £3,240,000 with the buyer's premium, about $4,188,393. At the time it was the highest price ever paid for an ancient coin at auction, beating the Pantikapaion stater's first record and any Roman piece by a wide margin.

Then the story turned. In February 2023, US authorities seized the coin on the basis that it had been looted from Greek soil — specifically from an area where Brutus's army was encamped in 42 BC — and sold with a fabricated provenance chain. The "old Swiss collection" language attached to the 2020 lot is, in the antiquities trade, well understood as code for "we cannot document where this actually came from." In March 2023 the coin was formally repatriated to Greece and is now in the National Archaeological Museum in Athens. Richard Beale, the director of Roma Numismatics, later pleaded guilty in a New York court to charges related to the consignment, and the firm itself closed in 2024.

For a collector reading this guide, the EID MAR is the single most important provenance parable in the modern market. The auction price stands as a historical figure — you will still see it cited as the world record — but the coin itself is no longer trade-able, and the case has changed how serious houses document gold antiquities at every level. The wider context of the coin's design is the Roman Republican coinage hub; the silver version of the same design is below.

3. The Syracuse tetradrachm signed by Kimon — about $3.05 million

A silver tetradrachm of Syracuse, Sicily, struck circa 405–400 BC, with the obverse die signed by the master engraver Kimon. The reverse is the city's facing-head Arethusa — a frontal female portrait with hair floating in water — technically among the most difficult compositions in ancient die-engraving and one of the benchmarks against which late-Classical art is read. The signed pieces are a small subset of the Syracusan output and the finest of them are treated, fairly, as small sculptures; Kimon and Euainetos signed the great Syracuse decadrachms in the same way.

This example, from the David Walsh Collection, realised CHF 2,737,000 — about $3,052,750 with the buyer's fee — at Numismatica Ars Classica's 77th auction in Zurich on 26 May 2014. It took the record for a Greek silver coin from the Akragas dekadrachm that had held it for less than two years (below). The two record sales share a house, an auction format, and a Zurich room with a lot of memory in it; the active high end of Greek silver basically operates from a single set of phones a few times a year. Sicily is the seat of the finest Classical silver, and the tetradrachm is the form it most often takes.

4. The Akragas dekadrachm — about $2.92 million

A silver dekadrachm of Akragas in southwestern Sicily, struck around 409–406 BC, just before the Carthaginians sacked the city. Roughly 43 grams of silver, about the diameter of a US half-dollar. The obverse shows two eagles tearing at a hare; the reverse, a quadriga with a crab beneath. About a dozen examples are known across museum and private collections. The strain in the iconography is the point — Akragas struck this coinage in its final years of independence, and the design reads, to a numismatist, as a city making a statement at the moment its options were running out.

The 2012 sale, from the Hunt Collection, made CHF 2,714,000 — about $2,918,810 with the 18% buyer's fee — at Numismatica Ars Classica's 66th auction in Zurich on 17 October 2012, and it held the Greek silver record until the Kimon Syracuse tetradrachm took it in 2014. The Hunt provenance matters: Nelson Bunker Hunt's ancient holdings were among the most carefully assembled American collections of the second half of the twentieth century, dispersed in stages from the 1990s onward. A Hunt pedigree is a piece of value in itself.

5. The Diocletian 10-aureus gold medallion — about $2.33 million

A unique 53-gram gold medallion of Diocletian, just under 40 mm across, struck for the emperor's decennalia in roughly AD 294 and worth ten aurei at face. It is the largest Roman gold coin ever offered at auction and, after the EID MAR repatriation, the auction record-holder for any Roman Imperial coin in any metal. The obverse carries a heavy, square-jawed bust of Diocletian; the reverse, a seated Jupiter. Medallions of this size were not currency — they were imperial gifts, donatives handed to favoured officials and generals on dynastic anniversaries, and they survive in tiny numbers, almost all in museums.

This example sold for $2,327,500 at the Classical Numismatic Group's Triton XXVI auction in New York on 10–11 January 2023, against a $500,000 estimate. The room understood what it was looking at — an artefact of imperial patronage that bridges the gold standard of Augustus and the later Tetrarchic reforms that would eventually produce Constantine's solidus. For collectors of the high end of Roman gold, the result re-priced the entire multiples-of-aurei category overnight.

6. The Hadrian sestertius — about $1.65 million

Roman sestertii are brass, not gold, and the surprise of this list is that one of them sits in the same price range as five-figure-weight gold medallions. A sestertius of Hadrian from 135–136 AD, exceptional condition and from the Roman bronze series that the connoisseur trade has always treated as the finest portrait art in Roman numismatics, sold for $1,648,805 at Numismatica Genevensis SA in Geneva in December 2008. It is the record for any Roman bronze coin and one of the few non-precious-metal ancient coins to clear seven figures.

The lesson here is one collectors learn slowly: condition compounds faster than material. A common late-Roman gold coin in average grade brings a few thousand dollars; a Hadrianic sestertius in mint state from a published collection has cleared a million more than once. The sestertius was a portrait medium — the large flan let engravers work at the scale of a small relief sculpture — and the surviving high-grade examples are some of the most desirable objects in the field. The wider story of the second-century imperial bronze is the Nerva–Antonine dynasty hub; how to value a coin like this is the valuation guide.

7. The Year 1 silver shekel of the First Jewish Revolt — about $1.10 million

A silver shekel of 14 grams, struck in Jerusalem in AD 66 in the first year of the Jewish revolt against Rome. The obverse legend reads "Shekel of Israel" with the date "Year 1"; the reverse, "Jerusalem the holy," with a stem of three pomegranates. Coins of this series were struck for only the four years the revolt held out before Vespasian and Titus took the city in AD 70. Year-1 shekels are the rarest of the run — the dies and the moneyer's hand are visibly still figuring out what the coinage was going to look like — and the example here was an early prototype with a documented provenance going back several decades.

Sold for $1,105,375 at Heritage Auctions in New York on 8 March 2012, it set the auction record for a Judaean coin at the time. The piece reads, more than almost any other ancient coin, like an explicit political document: a city under siege issuing its own money in its own language as an act of state-formation. The Vespasian "Judaea Capta" series struck a few years later from Rome answers it from the imperial side. The broader context lives at the Judaean coinage hub.

8. The Naxos tetradrachm of the Aitna Master — about $994,500

A silver tetradrachm of Naxos in Sicily from around 460 BC, attributed to the engraver known to scholars as the "Aitna Master" after his masterpiece for the city of Aitna. The obverse: a bearded Dionysos. The reverse: a seated Silenos in three-quarter view, drinking from a kantharos. The composition reads as drawing more than as die-engraving, and it is one of the half-dozen pieces routinely named as the highest art of Classical Greek coinage.

Sold for $994,500 with the buyer's fee at the Prospero Collection sale — the same January 2012 New York auction that first launched a Pantikapaion stater past $3.5 million — it set the auction record for a Greek silver coin until the Akragas dekadrachm overtook it later that year, and then the Kimon Syracuse tetradrachm overtook that in 2014. A high-end Sicilian-silver shelf is a chain of displaced records, each new sale clearing the last by enough to justify the cataloguing.

9. The silver EID MAR denarius — about $720,000

The same iconography as the Brutus aureus — EID·MAR, two daggers and a freedman's cap — but struck in silver. There are perhaps 100 silver denarius examples known across public and private collections, against the three gold pieces, which makes the silver version genuinely collectable rather than essentially unobtainable. Even so, exceptional examples have always traded above the rest of the Roman Republican market.

The current record sits at $720,000, set at Heritage Auctions' Long Beach sale on 3–5 May 2023, for an NGC-graded XF example with Fine Style. It is the only silver Republican denarius to have ever cleared half a million dollars at public auction. The historical importance of the type, the documented provenance of the specific specimen, and the post-2023 awareness around the iconic design — together those moved the silver Brutus into a price tier that the rest of the imperatorial silver series, even Caesar's Elephant and the Octavian portraits, has not reached.

10. The Umayyad gold dinar of Yazid II — about $6.03 million

Included with the asterisk that opened this guide. A gold dinar of the Umayyad caliph Yazid II, struck in AH 105 (AD 723) and bearing the inscription "mine of the Commander of the Faithful" — identifying it as made from gold from the caliph's personal mining concession somewhere in the Arabian peninsula. About 4.25 grams, no portrait (Umayyad reformed coinage is aniconic), all calligraphy. Roughly a dozen examples are recorded.

One example sold at Morton & Eden in London in April 2011 for about $6.03 million — the all-time auction record for an Islamic coin. A second came up at the same house in October 2019 and made about $4.78 million. The 723 AD date sits past the conventional end of the ancient world but before the medieval European numismatic tradition really begins, and serious lists handle the Umayyad gold either way. If you collect the late Roman and Tetrarchic gold this is the coin that sits one shelf along; if you collect medieval Islamic, it is the ceiling of your market. Either way, at the price it sold for, it deserves the entry.

Why these coins sell for millions

A pattern across the list. Every coin here is rare in absolute terms — single-digit or low-double-digit known examples, with most of those in public institutions. Every coin here commemorates something specific and named: the Ides of March, the Bosporan satyr, the Akragantine eagles, Diocletian's first decade, Hadrian's bronze, Jerusalem under siege. Every coin here is in exceptional condition for its age — none of these are worn examples that survived in a sock-drawer hoard; each has a flan and a strike that record what the dies actually looked like. And every coin here has a documented provenance going back decades, ideally to a named collector with a published catalogue.

Knock any one of those four out and the price falls by an order of magnitude. A Pantikapaion stater in fine but not exceptional grade is a low-six-figure coin. A silver EID MAR with no provenance is a six-figure coin with a problem. A common Hadrian sestertius in average condition is a $300 coin. The million-dollar threshold is what happens when rarity, importance, condition, and pedigree compound on a single object — and even then, the rooms that bid that high are small and the buyers know each other.

For a working collector, the practical takeaway is not "find a coin like these" — you almost certainly will not, and if you do, the attribution and provenance work to confirm it is the expensive part of the exercise. The takeaway is that the same four factors run the collectable market at every price band. A documented chain of ownership adds value to a $500 coin as much as to a $5 million one. Condition compounds at every grade. Specific iconography and named events command premiums over generic types. And rarity, when honestly assessed against public databases like the ANS Online Coins of the Roman Empire or recent acsearch results, is the foundation under all of the others. The valuation guide walks through how to apply that lens to a coin you actually own; the insurance guide covers what to do once a collection has crossed the threshold where it needs documenting for outside parties.
