Another sports card collector just hit the JACKPOT -- pulling a rare 1-of-1 LeBron James jersey card ... and he's already getting some huge offers to sell!

It all went down Thursday night at Jaspy's Case Breaks card shop in Hermosa Beach, CA -- which was hosting a "live break" of a box of 2019-20 Panini Immaculate Premium Edition cards.

Each individual box runs about $2,500 -- and contains ONE pack with SIX cards. High stakes card collecting!!!

Jaspy's was hosting an event where collectors could buy rights to cards based on an NBA team -- for example, you could buy the Houston Rockets for $100 and any card pulled featuring a player on the Rockets would belong to you.

Huge upside, but if the pack contains no Rockets players, you get nothing. Get it? Great.

In this case, a collector purchased the rights to the Lakers cards for $70 -- and man, BEST $70 INVESTMENT EVER!!
