The phrase denotes a complete listing of trading cards available in a specific baseball card set released in 2021 under the “Elite Extra Edition” brand. This list typically includes details such as player names, team affiliations, card variations (e.g., parallels, autographs, memorabilia cards), and serial numbering information. For example, a particular item on this list might read “Wander Franco Autograph, serial numbered to 99.”
Such a document is important to collectors and investors for several reasons. It provides a definitive guide for identifying and tracking the cards within the set, enabling collectors to complete their sets, assess the rarity and value of individual cards, and inform purchasing decisions. Historically, checklists have evolved from simple printed inserts to comprehensive online databases, reflecting the increasing complexity and sophistication of the trading card hobby.
