Quinn Brown’s $3.07 thrift-store find sold for $89,600 at Sotheby’s Summer Sports Classic on July 20, 2026. Brown, 19, bought the yellow warmup jacket at the Hillsboro Goodwill Outlet in January 2026. Sotheby’s authenticated it as a Lakers jacket Wilt Chamberlain wore during the 1972 NBA Finals, matching its stitching to photos from the series. Brown said he plans to invest the proceeds.
