Kobe Bryant pre NBA auto

I spent the week with the 1996 McDonald's highschool All American teams when I was a young teen. I collected each signature on this ball and the top prize was the entire team East/West including Kobe Bryant. This was after he graduated from Highschool but had not yet entered the NBA draft. If memory serves he attended prom with Brandy just before or after I got this.

Cool story and all and a very unique and special ball. How would you even go about authenticating or possibly selling something like this?
