MICHAEL JACKSON'S 'MOTOWN 25' GLOVE FOR SALE: 'Holy Grail' of MJ memorabilia headed for auction in NY.

      "There is no question it is the Holy Grail of Michael Jackson," said Darren Julien, president and CEO of Julien's Auctions, the company behind the sale at New York's Hard Rock Cafe.     

       Julien's estimates the value of the glove conservatively at $40,000-$60,000 but expects it to sell for much higher.

       "I have talked to more than 20 very interested serious clients all over the world who will be bidding on the piece and all have expressed interests over $200,000-$300,000," Julien said.

      Roughly 80 Jackson lots will be up for bid, consisting of pieces that come from friends and family who were given the items by Jackson himself, Julien said. The auction company values the MJ collection at $80,000 to $100,000 but Julien said its pre-auction estimates are intentionally very conservative to help generate interest.

       Julien's had been preparing for a huge auction of Jackson memorabilia in April – two months before the singer's death – but it was canceled after an agreement with Jackson, who had filed a lawsuit demanding the return of certain items. During the promotion for that sale, Julien's had amassed a large database of Jackson collectors from Asia to the Americas.

       Collectors can also bid for an Elvis Presley ring, James Brown's suits and Kurt Cobain's finger prints, taken from the late Nirvana front man when he was arrested for trespassing while intoxicated in 1986 at the age of 19.
