I know they're legit - CMM used to work in telecom sales, in the very early days of cell phones, and they would give the pro team athletes in his area (Houston) free cell phones; he got a lot of perks in return and has other items like a personally addressed signature from Julius Erving on his photo, and in the garage there are shoes from some pro basketball player, I forget which. He met a lot of pro athletes in those days.
On the other hand - if anything had been REALLY valuable, he would have mentioned it.
