Signature Chefs Auction Dates Join the March of Dimes for this year’s Signature Chefs Auctions held in over 200 cities across the country. Last year, these events raised over $15 million to make sure that all babies are born healthy. This unique and fun dining experience – where top local chefs present their signature dishes in a tasting format - has raised more than $ 89million for the March of Dimes since the first Chef’s Auction was held in 1989.
