Gandolfini donated about two dozen outfits he kept from the recently wrapped HBO series, The Newark (N.J.) Star-Ledger said.
His character's iconic bathrobe sold for $11,000 after Gandolfini spurred on the bidders stalled at $9,000 by shouting, "When I die, it'll be worth a lot of money."
The shirt his character wore in the show's opening credits also sold for $11,000.
Proceeds from the sale of Gandolfini's personal items are to benefit the Wounded Warrior Project, a nonprofit organization that helps soldiers severely wounded in Iraq and Afghanistan, the newspaper said.
The sale of Gandolfini's costumes were part of a Christie's Pop Culture sale.
The Star-Ledger said dozens of other "Sopranos" costumes worn by other actors on the show were also sold courtesy of the Hollywood memorabilia vendor The Golden Closet at Wednesday's auction.
