The 2019-20 Upper Deck Allure Checklist is an essential document for collectors of cards, memorabilia, and other sports collectibles. It provides a comprehensive list of every item that is available in the current year’s collection, which helps collectors to stay up-to-date on the latest releases and acquisitions. This checklist also serves as a reference guide when collecting, as it provides descriptions of each item, its condition, and its rarity. It also includes an estimated value for each card or memorabilia piece.
