The CNFans Reddit community has established a dedicated platform for analyzing the value retention of luxury goods, particularly focusing on the LV Damier Ebene collection. This platform is powered by the CNFans Spreadsheet, which serves as a comprehensive database for tracking and analyzing the resale value of various Louis Vuitton items.Within the Spreadsheet, community experts maintain a "Vintage Monogram Value Retention Ranking" that provides insights into the value retention of the iconic Speedy 25 bag over the years. They meticulously track and graph the second-hand premium rate of the Speedy 25, allowing users to visualize how the bag's value changes with time.In addition to the Speedy 25, the community also analyzes the circulation speed of the Neverfull bag by region. This regional analysis helps users understand how the demand and supply dynamics vary across different geographical locations, affecting the resale value of the Neverfull.Users of the platform can input their purchase price and the duration of use, and the Spreadsheet generates a "Resale Value Assessment Report." This report includes the impact of maintenance suggestions on the value retention rate, providing users with actionable advice on how to maintain their items to maximize their resale value.The Spreadsheet also has the capability to access an "Auction Market Database," which references成交 data from platforms like Sotheby's. This feature allows users to compare the resale values of their items with actual auction results, offering a realistic perspective on the market value of their possessions.For more detailed information and to access the CNFans Spreadsheet, please visit the following external link: CNFansSheet.
