Celebrity presenters and phone bank volunteers, including the cast of The Sopranos, Chelsea Clinton, Whoopi Goldberg, Karlie Kloss, Chris Martin, Seth Meyers, Ben Stiller and others also signed exclusive, limited-edition metallic gold and silver concert posters for the auction, which runs from now through Dec. 20.

Estimated values on auction packages range from $5,000 to $121,000. All net proceeds will go to the Robin Hood Relief Fund.

Meanwhile, "12-12-12" concert organizers are readying a digital and CD release of the show, which will also go to the cause.

Sandy struck the eastern part of the United States in late October, damaging hundreds of thousands of homes and killing at least 125 people.
