Someone who witnessedLeBron James break the NBA scoring record earlier this year is absolutely thrilled to have kept the ticket ... 'cause TMZ Sports has learned it's now expected to fetch a few THOUSAND dollars at auction next month!!!
The $92 stub that was used by a fan to watch James pass Kareem Abdul-Jabbar at Crypto.com Arena back on Feb. 7 just hit the block this week ... and Heritage Auctions experts say it could ultimately sell for over $5,000.
The ticket for the historic Lakers vs. Thunder tilt is awesome ... it's from the 2nd row of section 209 -- and it was given a Mint 9 grade by PSA.
As for the potential sale price -- it seems steep, considering nearly 20,000 people were there and the game happened just a few months ago -- but as we previously reported, it's far from the only thing that night that is worth a ton to NBA collectors.
You'll recall ... Chris Ivy, the director of sports auctions at Heritage Auctions, told us back in February he believes 'Bron's game-worn jersey from the night could land $3 MILLION if it ever made it to the auction block.
When it comes to the ticket, bidding is already up over $2,000 -- but the final gavel won't hit until next week ... good luck!!!
