The Rip Sheet’s Chase Index
A live sports-card pricing index that ranks players by their share of scarce-card value across recent releases.
Field notes
The index divides the selected player board into shares based on autographs, numbered parallels, and rare inserts, while excluding plain base cards and ordinary inserts. Its basketball edition lists 50 players and reports both rank movement and evidence breadth; Cooper Flagg leads at 20.84% with 43 comparable groups behind the position. A linked beta tool extends the same market logic to live breaks by letting users build a box mix, mark spots as sold, and track remaining value.
