There was a real nirvana set lost that sold for 22 thousand, the guys were talking about it some where on this site.
Should have bought the set list.
Lot 111, the jacket they say MJ worn when he met Nelson Mandela, has a signature so faded that it probably doesn't add anything to the value. If that is truly the jacket he wore to meet with Mandela and it photo-matches, I think that the jacket sold for a fair price for both the buyer and seller.
The autograph on the signed V guitar, Lot 106k doesn't look right to me.
