Imagine spending $515 on a spot in a card break - and ending up with something worth more than $8 million. The one-of-one Cooper Flagg card featuring his autograph and the patch from his NBA debut just sold for a staggering price, putting it among the most expensive NBA cards ever sold. If you pulled a card worth millions, are you selling it immediately - or hanging onto it? #CooperFlagg #MFFL #DallasMavericks #SportsCards #KRLD audacy.com/krld/news/local/c…
