Overview - The article discusses the deep analysis of a highly collectible set of the fourth edition of the Renminbi, which includes a complete set of all same-numbered notes in a premium edition, issued by the People's Bank of China, with a limited release of only 99 sets priced at 98,000 yuan [1][7]. Core Value Analysis - Historical significance and scarcity due to withdrawal from circulation: The fourth edition of the Renminbi represents a key historical transition in China's economy and has been officially withdrawn from circulation since 2018, leading to a decrease in its availability and an increase in value due to supply-demand dynamics [3][6]. - Same-numbered rarity: The set features notes with identical serial numbers, which are extremely rare and highly sought after by collectors, further enhancing its value [6]. - Rich variety and potential as "king of notes": The collection includes all nine denominations and 14 versions of the fourth edition, including rare 1980 versions of 50 yuan and 100 yuan, which are already valued over 10,000 yuan each [6][7]. - Top condition and authoritative certification: The notes have been rated 69 out of 70 by a professional grading agency, indicating excellent preservation, and come with a certification from the People's Bank of China, ensuring authenticity and limiting the risk of counterfeiting [5][7]. Investment and Collection Prospects - Hotspot for capital speculation: Recent trends indicate that certain denominations, such as the 2 yuan note, have gained significant attention, while the 1980 versions of 50 yuan and 100 yuan show strong appreciation potential [7]. - Long-term holding value: As a "closed currency type," the limited availability of the complete same-numbered set (only 99 sets) suggests that its value will likely increase over time, aligning with the principle that scarcity drives appreciation [7]. - Target audience: The collectible appeals to high-end collectors seeking extreme rarity and perfect condition, asset allocators looking for alternative investments to hedge against inflation, and history enthusiasts interested in the cultural significance of the notes [7].
