You get 24 packs/box, 5 cards/pack.  Look for autographs, game worn jersey cards, low serial numbered cards, etc.  I think it is rare, but you could possibly pull a Kobe Bryant or Michael Jordan autograph basketball card out of a pack.  Check your checklist or google or an old Beckett, to see, who else, could be in this box.  Fun to open, but take your time, because the cards will be glossy.  It might be a great investment, by just leaving the box sealed.  Good luck!  See scan.
