Goodwill's $3.07 Wilt Chamberlain Jacket Brings $89,600 at Sotheby's

A thrift reseller in Oregon paid $3.07 for a Wilt Chamberlain warmup jacket at a Portland Goodwill. Sotheby's authenticated it by photomatching — comparing stitching and measurements to archival photos — tying it to three games and the 1972–73 season. It sold July 20 for $89,600, well below the $150,000–$250,000 estimate. How it reached Goodwill remains unknown.
