Organised by CharityBuzz, the auction will benefit the Robert F Kennedy Memorial, a non-profit group that provides funding to human rights causes.
Breakfast or tea for four with Greenspan and his wife is expected to raise at least $5,000, while other big names offering their time for the cause include Robin Williams, Larry King, skater Tony Hawk, and former CIA spy Valerie Plame.
Bidding ends on April 6th.
