search Ebay with highest price first to see it
I have watched the 89 homecoming show a few times and don't remember the vest at all, but if it appears in the vid it is probably worth about $1000 not $11,000 crazy people

The sad thing is that of the first 20 items in this search 10 are counterfeit, 2 are of questionable authenticity, 1 is incomplete and only 7 are genuine with 1 grossly overpriced.

I used to love to buy memorabilia but the market is just full of liars and thieves now.
