Well, here's your chance -- the actual basketball that Kareem Abdul-Jabbar used to score his 38,387th point in his final regular-season game just hit the auction block ... and TMZ Sports is told it could sell for as much as $500,000!
Of course, KAJ scored the monumental basket on April 23, 1989 -- the last regular-season game of his legendary career -- when Kareem's Lakers took on the Seattle SuperSonics at the Forum in Inglewood.
Abdul-Jabbar played 26 minutes ... scoring 10 points on 5-6 shooting. He also had 6 rebounds, 3 assists and a blocked shot.
Those 10 points put Kareem's career regular-season total at 38,387 ... leaving him thousands of points ahead of Wilt Chamberlain, the second-leading scorer at the time.
