A sports card with the signatures of two of the greatest basketball players ever sold for a record price this weekend.

Not only did the Jordan/Bryant card, which was called a Holy Grail by ESPN, break a record, but it is the second most expensive sports collectible, second only to Babe Ruth’s 1932 World Series “called shot” jersey. That sold for $24.12 million last year.

An anonymous bidder pays a record £9.56m ($12.9m) at an auction for a basketball card signed by Michael Jordan and Kobe Bryant making it the most expensive sports collectible card in history.
