Value of this

[Hank]

Hey, I have a basketball signed by all of the Kings players the very first year they came to sacramento and I was wandering what its value is. My dad went to a practice I believe and it was signed by all of the players, he has pictures of it being signed as well.

Sounds like something for antiques roadshow Seriously though, there are appraisers that specialize in that sort of thing.
