How we rank

Ranked by the highest publicly reported sale of each item, in US dollars, as of October 9, 2026. We list only sales we could confirm in a published source, so some aisles show fewer than 10. Each aisle's scope is noted below its title. Our editors may leave out an item.

Editorial list. Prices are past sale results as reported by auction houses and news outlets, shown for information only. They are not appraisals, price guides, or offers to buy or sell, and they do not show what any other copy is worth. Private-sale prices are as reported and not verified by Showcase Rack. Photos marked "Representative example" show the same kind of item, not the piece sold. Brand, team, player, grading-company and auction-house names are used only to identify items; Showcase Rack is not affiliated with or endorsed by any of them. Spot an error?
