Historic jerseys from the careers of Michael Jordan, Colin Kaepernick and former US President Barack Obama have set sales records at an auction of sports memorabilia.
The official National Basketball Association jersey given to Jordan on the day he signed with the Chicago Bulls in 1984 sold for $US320,000 ($A430,000), the highest price paid for a Jordan jersey.
Jordan held up the red-and-white jersey, which featured his name and the number 23, at his first news conference as a member of the Bulls.
He went on to become the heart of the Bulls dynasty that won six NBA championships in the 1990s.
Also at the auction, a basketball jersey worn by Obama in 1979 during his senior year at Punahou School in Hawaii sold for $US192,000 ($A258,000), a record for a high-school jersey sold at auction.
The white mesh jersey also features the number 23.
And a white number 7 jersey worn by former National Football League quarterback Colin Kaepernick in 2011, during his debut game with the San Francisco 49ers, sold for $US128,000 ($A172,000), making it the most expensive NFL jersey sold at auction.
Kaepernick has been one of the most prominent and controversial sports figures in the United States.
His decision in 2016 to kneel during the playing of the national anthem in order to put a spotlight on police brutality helped inspire the Black Lives Matter movement. Critics said he was disrespecting the United States and its flag.
