From ESPN:

"The Upper Deck rookie Patch Autograph set typically produced only 99 of each card, which included a patch of jersey from the player's rookie season and an autograph on the card. This particular James card, however, was part of the Patch Autograph Parallel set that only produced the same number of cards corresponding to the number on the player's jersey.

With James wearing No. 23, there were only 23 of this card produced, and since it was graded as a 9.5 mint gem by Beckett grading service, it was one of only two of these particular cards graded that high."

"There are only two of them, one of them is in private hands and the other was up for auction," Goldin said to ESPN. "So this really was the single best LeBron card that somebody could have hoped to get. It was very active bidding, a lot of bidders, and we're happy with the results."

The record sale tops the previous record set in May, when a gem mint Bowman Draft Chrome Red Refractor Mike Trout signed rookie card sold for $922,500.
