A high-profile sports relic, Wilt Chamberlain’s yellow warmup jacket from the 1972 NBA finals, was discovered in a Portland-area Goodwill bin by teen reseller Quinn Brown for just $3.07 and later sold for $89,600 at Sotheby’s.

Sotheby’s conducted the auction with an armored pickup and used online photo comparisons to verify provenance and support a photomatch authentication.
