Michael Jackson's lucrative afterlife has just begun

Michael Jackson, the man they called "The King of Pop," worried he would end up dead like "The King of Rock 'n' Roll" Elvis Presley, the father of his ex-wife Lisa Marie. Jackson's worries are proving to be prophetic.

Already, the price of Jackson memorabilia is soaring. Pop culture expert Gary Sohmers, who also is an appraiser on "The Antiques Roadshow" told DailyFinance that he saw a reproduction of a Jackson autograph fetch $1,400. Jackson's actual autograph fetches about $400 to $800. Sohmers, a former music promoter who runs allcollectors.com, cautions would-be collectors against buying into Michael mania.
