NEW YORK (AP) — A rare jersey from Jackie Robinson's historic rookie season with the Brooklyn Dodgers 70 years ago could be available for someone with a few spare millions.

The jersey, part of a Heroes of Sports offering by Heritage Auctions, has been certified by Mears, one of the top memorabilia authentication companies. It is accompanied by a letter from Robinson's widow, Rachel, saying it is the one he brought home at the end of the 1947 season. That's when he became the first black player in the majors and earned Rookie of the Year honors.

The online auction opened Friday and closes at 11 p.m. on Nov. 19. The entire collection is from one owner and can be viewed on Heritage's website .

Chris Ivy, Heritage's director of sports auctions, says the Robinson jersey has been valued at more than $3 million. He wouldn't be surprised to see it exceed that.
