B Bennett / Bruce Bennett / Getty It's been over 20 years since Wayne Gretzky last played in the NHL, but The Great One is still breaking records. A 1979 Gretzky O-Pee-Chee Gem Mint rookie card sold for $1.29 million on Thursday, according to Heritage Auctions. There are only two specific 1979 Gretzky O-Pee-Chee cards to receive a Professional Sports Authenticator 10 gem mint status, making it extremely rare. It's the first hockey card to surpass the $1-million mark. It's also the sixth-most expensive sports card ever sold, trailing a 2009 Mike Trout ($3.9M), a 1909 Honus Wagner ($3.3M), a 1952 Mickey Mantle ($2.9M), a 2013-14 Giannis Antetokounmpo ($1.9M), and a 2003-04 LeBron James ($1.8M), according to a list made in November by Groove Wallet.
