An autographed 1979 O-Pee-Chee Wayne Gretzky rookie card, graded a nine with a 10 autograph grade by card grader Professional Sports Authenticator (PSA), sold for $540,000 including buyer's premium in Fanatics Collect's May Premier Auction. It's the most ever spent on an autographed hockey card.

Gretzky's O-Pee-Chee rookie card is no stranger to large sums: Four different copies, all graded 10s by PSA, have sold for $720,000, $1.2 million, $1.29 million and $3.75 million since December 2020. None of those copies, however, were signed by The Great One.
