A Parisian antiquarian discovered on the evening of Friday, September 18 that ancient coins and gold louis d'or, stored at his home in the 14th arrondissement, had gone missing. The loss is estimated at around one million euros, a significant amount for a private collector. The louis d'or is a historical French gold coin that was commonly used during the 17th and 18th centuries, often valued for both its historical significance and its precious metal content. The antiquarian, who is known in Parisian circles for his extensive collection of historical artifacts, found the theft had occurred without any signs of forced entry. This detail has raised questions among investigators about how the thief managed to access the property undetected. The absence of forced entry suggests the possibility of an inside job or someone with prior knowledge of the home’s security. Authorities have been notified, and an investigation is currently underway. The police are examining surveillance footage and speaking with neighbors to determine how the theft occurred. The antiquarian has not yet commented publicly on the incident but has expressed concern over the security of his personal property. This incident highlights the vulnerability of private collections, even in secure environments. While such thefts are rare, they underscore the importance of robust security measures for valuable historical items. The case is being closely watched by both local authorities and the broader numismatic community, which values such artifacts for their cultural and monetary worth.
