Bryant took 46 shots and added 20 free throw attempts ... dropping 81 points with just 3 turnovers. What's even more incredible is only 2 other Lakers scored more than 10 points!
Of course, Bryant's squad won the game -- a sellout at Staples Center -- and Kobe said of it all afterward he couldn't have have imagined dropping that much "not even in my dreams."
We're told a portion of the proceeds from the auction will be donated to the MambaOnThree Fund -- a charity set up to help the families of the other passengers that died in the tragic helicopter crash that killed Bryant and his 13-year-old daughter, Gianna, on Jan. 26.
Bidding on the amazing piece has already begun (it's currently at $1,500) ... and is expected to stay open until later this month.
