I have a Michael Jordan card and curious the value?

It's a 1986 Fleer # 57 Jprdan rookie card that has been autographed in blue ink on the front and certified by Upper Deck and comes with a certificate of authenticy from Upper deck and a hologram imprinted on back of card. I don't believe it to be an insert offered in the packs in 2007 but a card that was sinned at a show with upper deck representatives present. I have been trying to determine a value but still insure?
