Donruss Elite checklists are essential for any collector looking to build a complete set of cards. This checklist provides a comprehensive list of all the various cards in the collection, making it easy to identify what is needed in order to complete the set. Having this checklist is important because it allows collectors to stay organized and up-to-date on what cards they already have and which cards are still missing. It also allows them to accurately track their progress as they work to finish the set.
