For collectors, numismatists and auction houses, the case raises more than the familiar issue of illicitly removed archaeological material. It illustrates a fundamental distinction in any cross-border ownership dispute: <strong>the State may have a strong legal claim to objects recovered from a particular archaeological site, but it must still establish that the individual object in question came from that site<\/strong>.<\/p>\n<h2>A London auction suspended, without a reported ownership judgment<\/h2>\n<p>According to the <a href=\"https:\/\/fr.linkedin.com\/posts\/douanefrancaise_une-monnaie-romaine-du-tr%C3%A9sor-de-activity-7516858905910763520-__Zx\">French Directorate-General of Customs and Indirect Taxes (DGDDI)<\/a>, a Roman gold coin was about to be offered at auction in London. Following intelligence supplied by France&#8217;s National Directorate for Customs Intelligence and Investigations (DNRED), French and British services worked together to locate the object. The Metropolitan Police secured suspension of the sale at the French authorities&#8217; request. Having been informed that France regarded the coin as part of the Lava Treasure and as State property, its holder agreed to relinquish it.<\/p>\n<p>The DGDDI described the coin as returned to France and stated that it would be repatriated and entrusted to the French Ministry of Culture. Its public announcement did not identify the auction house, publish a detailed numismatic description or set out the underlying provenance evidence. Nor did it refer to a judgment by a British court determining ownership.<\/p>\n<p>That is an important distinction, not an objection to the outcome. Voluntary surrender following cooperation between police authorities is a practical means of resolving a case; it does not establish that a contested French ownership claim has been judicially examined under the law applicable in England. The announcement records the position of the French authorities and the holder&#8217;s decision. It does not make the underlying evidence publicly available for independent evaluation.<\/p>\n<h2>What the French Court of Cassation decided in 1997<\/h2>\n<p>France&#8217;s claim to material recovered from Lava has a substantial legal history. On <a href=\"https:\/\/www.legifrance.gouv.fr\/juri\/id\/JURITEXT000007071174\">21 May 1997, the Criminal Chamber of the French Court of Cassation (*Cour de cassation*) delivered judgment no. 96-80.618<\/a>, dismissing appeals against convictions relating to the misappropriation and receiving of maritime wreck property (<em>d\u00e9tournement et recel d&#8217;\u00e9pave maritime<\/em>). The Court upheld an order returning ancient gold coins seized in those criminal proceedings to the Minister of Culture.<\/p>\n<p>The courts applied Articles 23 and 24 of the French decree of 26 December 1961, under which maritime wrecks of archaeological, historical or artistic significance whose owners were unknown or could not be traced belonged to the State under the conditions laid down in that legislation. The fact that the objects were coins did not take them outside those special rules. The current French framework is principally found in <a href=\"https:\/\/www.legifrance.gouv.fr\/codes\/section_lc\/LEGITEXT000006074236\/LEGISCTA000006159955\/\">Articles L. 532-1 and L. 532-2 of the French Heritage Code (*Code du patrimoine*)<\/a>. It governs maritime cultural property (<em>biens culturels maritimes<\/em>) and State ownership in specified circumstances.<\/p>\n<p>The 1997 decision is not, however, a ruling on every Roman coin of a type represented in the Lava assemblage. It concerned <strong>the coins actually seized and examined in that criminal case<\/strong>. The factual findings went well beyond an expert&#8217;s classification of the issues: they included evidence concerning diving in the Gulf of Lava, the unusually large volume of gold coins reaching the market, the circumstances of acquisition by specialist dealers, and, for certain coins, surface concretions. The trial courts assessed a body of evidence relating to particular objects and transactions.<\/p>\n<p>To use that judgment as a conclusive presumption that every comparable coin now circulating internationally was recovered at Lava would extend it beyond its facts and its legal holding. The decision establishes the consequences of a provenance found proved in that litigation; it does not eliminate the need to prove provenance in another case.<\/p>\n<h2>Identifying a coin is not the same as identifying its findspot<\/h2>\n<p>Numismatic expertise may identify a ruler, mint, denomination, issue and even a shared obverse or reverse die with remarkable precision. These findings tell us how a coin was made. <strong>They do not necessarily tell us where that particular specimen was buried, lost or discovered.<\/strong> Two coins struck from the same dies could have followed different routes across the Roman world. A rare issue may be strongly associated with a particular find without every surviving example having originated in it.<\/p>\n<p>An individual link to a hoard or underwater assemblage therefore requires a further enquiry. Depending on the evidence, the relevant material may include earlier photographs of the identical specimen, distinctive striking or surface features, auction records, scholarly inventories, documentary references, correspondence and the circumstances in which the coin first entered the modern market. A combination of consistent circumstantial evidence may be sufficient; an original excavation record is not invariably necessary. But the reasoning must be specific enough to be explained and, where disputed, tested.<\/p>\n<p>This does not suggest that French investigators lack evidence concerning the London coin. The point is narrower: <strong>the DGDDI&#8217;s public statement does not itself demonstrate, for an external reader, the provenance of that particular specimen<\/strong>. Equally, a long chain of auction invoices is not necessarily conclusive proof of valid title if the coin was previously removed from property vested in the State. The enquiry must be conducted in both directions, distinguishing numismatic attribution, archaeological provenance and legal ownership.<\/p>\n<h2>French recovery efforts abroad: different objects, different legal routes<\/h2>\n<p>The London case follows another recovery involving Lava. On <a href=\"https:\/\/www.culture.gouv.fr\/presse\/communiques-de-presse\/remise-a-la-france-par-la-norvege-d-une-monnaie-romaine-provenant-du-tresor-de-lava-en-corse-rachida-dati-ministre-de-la-culture-salue-la-c\">4 September 2025, Norway returned to France an aureus of Quintillus<\/a>, struck at Milan in AD 270 and identified by the French Ministry of Culture as belonging to the treasure. Norwegian police and judicial authorities cooperated before a contemplated sale, and the coin was handed over at the French Embassy in Oslo. That official announcement provided an unusually precise identification of the issue; the October 2026 London statement does not contain comparable detail.<\/p>\n<p>French public bodies have also obtained the return of works whose ownership rested on archival records rather than an underwater find. In <a href=\"https:\/\/www.cnap.fr\/actualites\/evenements\/le-retour-dun-portrait-de-napoleon-iii-dans-la-collection-du-cnap\">March 2026, the Centre national des arts plastiques (Cnap) announced the return of a *Portrait of Napoleon III* by Alexandre-Marie Roch\u00e9<\/a>, identified when offered by an auction house in Barcelona. The Cnap relied on documentation demonstrating that the painting belonged to the French State and had once been deposited at a French prefecture. The Spanish auction house acted as an intermediary with the holder, making an agreed return possible.<\/p>\n<p>On <a href=\"https:\/\/www.arch.be\/index.php?a=2025-10-21-la-belgique-restitue-a-la-france-plus-de-300-documents-d-archives-historiques-de-l-epoque-napoleonienne&amp;l=fr&amp;m=actualites&amp;r=toutes-les-actualites\">3 June 2026, Belgium handed France more than 300 Napoleonic-era archival documents<\/a>. The return followed an investigation triggered by public archives appearing on collectors&#8217; sales platforms and involved Belgian police and judicial authorities. The documents&#8217; public archival status, not the law of maritime archaeology, was central to the case.<\/p>\n<p>In <a href=\"https:\/\/www.cnap.fr\/en\/actualites\/evenements\/return-artwork-les-internes-de-saint-sauveur-jecheskiel-david-kirszenbaum\">October 2025, a Salzburg museum agreed to return *Les Intern\u00e9s de Saint-Sauveur* by Jecheskiel David Kirszenbaum<\/a> to the Cnap after research established that the painting belonged to France. The work is to remain on display in the Austrian museum for five years. Recognition of ownership and immediate physical relocation need not coincide.<\/p>\n<p>Agreement is not inevitable. In <a href=\"https:\/\/www.cnap.fr\/actualites\/evenements\/32-restitutions-en-5-ans-le-cnap-au-service-du-patrimoine\">a review published in 2024, the Cnap described the difficulty of recovering Kees Van Dongen&#8217;s *Portrait d&#8217;Anatole France*<\/a>, identified in connection with a Christie&#8217;s London sale in 2021. This was the position reported by the institution at that time, not a claim about the case&#8217;s current procedural status. It nevertheless illustrates why a documented State claim does not always result in voluntary surrender.<\/p>\n<p>These examples should not be treated as interchangeable precedents. A missing State-owned painting, public archives, and an ancient coin said to come from a maritime find raise different questions of legal title and different evidential issues. Even a strong French ownership claim must be assessed in light of the law and available procedures in the country where the object is held.<\/p>\n<h2>Responding to a French claim: investigate rather than assume<\/h2>\n<p>For an international collector, a specialist dealer or an auction house, an assertion of French title calls for serious enquiry. The object should be identified precisely; the alleged link to a find or public collection should be documented; the chain of possession should be reviewed; and the legal basis of France&#8217;s claim should be examined. Where an object is located in England, its recovery may additionally raise questions of English law, private international law and the procedures available to the parties. A statement from a French administrative authority is not, by itself, a British court order.<\/p>\n<p>These precautions are best taken before cataloguing and sale. Records kept under French dealers&#8217; traceability requirements, including the <em>livre de police<\/em> (dealers&#8217; register), may prove useful but are not a substitute for valid title or proper provenance research. Separate <a href=\"https:\/\/fournol-associes.com\/en\/art-market\/french-customs-cultural-property-evidence-origin\/\">French customs obligations concerning evidence of origin for cultural property<\/a> can also arise when coins and antiquities circulate through France.<\/p>\n<p>The London recovery demonstrates the practical effectiveness of cooperation between French and British authorities. It should not obscure the principle on which a legally persuasive restitution claim ultimately depends: <strong>a State&#8217;s entitlement to material from an archaeological site does not establish, without individualised evidence, that every similar item on the market came from that site<\/strong>. Proper proof protects cultural heritage. It also makes State claims capable of meaningful examination by the people asked to surrender their property.<\/p>\n<h3>About the author<\/h3>\n<p>An article written by\u00a0<a href=\"https:\/\/fournol-associes.com\/en\/firm\/our-team\/alexis-fournol\/\"><strong style=\"font-style: inherit;\">Alexis Fournol<\/strong><\/a>, Attorney at Law and Partner at Fournol &amp; Associ\u00e9s.<\/p>\n<p>Alexis Fournol advises French and international collectors, art market professionals, artists, estates and institutions on art-market, cultural property and ownership disputes.<\/p>\n<h3>How Fournol &amp; Associ\u00e9s can assist<\/h3>\n<p>Fournol &amp; Associ\u00e9s advises international collectors, numismatists, dealers and auction houses on French cultural heritage law, title disputes, antiquities provenance, customs seizures and cross-border restitution.
