How the research works
Ripbin monitors raw eBay listings for serial-numbered rookie cards daily and computes outlier-trimmed price comps for each card. Our monthly picks combine that market data with a simple screen: an improving young player, a team being built around him, and a card with a hard supply cap — ideally from a terminal set that will never be printed again. Full methodology is included in each report.
