Wayne Gretzky practice used stick with the Coyotes

[MASTERP]

Does anybody know the real world value on a practice used Wayne Gretzky stick while here in Charleston, SC 4-5 years ago? His actual stick taped up, used during the practive, and without an autograph. Pro Stock stick ofcourse.

I have a friend who owns it and has pictures taken during the practice of Gretzky using it. Same time that Coffey and Fuhr were coaching for the Yotes.

Thanks for any help.
