A Swiss tech heiress, 20-year-old Jolina Gisèle, is reportedly putting a large Pokémon trading-card collection up for sale. According to the accounts provided, Gisèle is described as having started collecting Pokémon cards at age seven and has built what is claimed to be the world’s largest collection. Experts cited in the reporting value the collection at about £50 million. The sources describe the collection as extensive enough to be widely known under nicknames such as “Pokémon princess,” highlighting her long-term involvement with the hobby. The reporting focuses on the origin and scale of the collection and on the estimated market value supplied by experts, but it does not provide additional verified details about auction terms, where the sale will occur, or whether the valuation represents a confirmed market price versus an appraisal. Overall, the information centers on the proposed sale, the size of the collection as claimed, and the estimated valuation figure.
