The Value of a 1992 Dream Team Basketball

Hi everyone,

A friend of mine wants to sell a 1992 NBA Dream Team basketball, but is unsure of how much he should ask for. I guessed around $2,000 - $3,000 US dollars. Some of the players who signed the basketball include:

Karl Malone, Utah
Chris Mullin, Golden State
David Robinson, San Antonio
Michael Jordan, Chicago
Clyde Drexler, Portland

SECOND TEAM
Scottie Pippen, Chicago
Charles Barkley, Philadelphia
Patrick Ewing, New York
Tim Hardaway, Golden State (?)
John Stockton, Utah

The basketball itself is in mint condition, and has been preserved in a plexiglass case.

If you guys could give me some price ranges of the value this ball, I would really appreciate it.

Thank you very much.
