In 2022, a Tunisian citizen was arrested in Oslo when he tried to sell 30 Carthaginian bronze coins to a local antiques dealer. The dealer had previously alerted the police after receiving an email inquiry asking him whether he was interested in buying a ‘large number’ of Punic coins from an alleged underwater find, presumably a hoard, off the coast of Tunisia. The University of Oslo’s Museum of Cultural History, which cooperates with law-enforcement agencies and the authorities in cases involving illicit cultural artefacts, assisted with the identification of the coins. Eventually, the latter were returned to Tunisia, and Norwegian prosecutors dropped the charges against the Tunisian national. This article discusses the relevant legal framework of the case and the process that unfolded from the time when an attempt was made to sell the coins until they were returned to their country of origin. The broader numismatic implications of this find are also examined.
