Does anybody know what they are worth?

I have an autographed basketball signed by Magic Johnson, Kareem Addul Jabbar and James Worthy. Does anyone know how much it's worth? Also have a pair of size 14 autographed Chucks signed by Dwayne Wade and a Minnesota Timberwolver's white jersey signed by Kevin Garnett. I won these in a GQ Sports Memorabilia Sweepstakes. Total value was $5000 but can anyone tell me how much each one amounts to individually?
