Christie's promises to release more details about the items available to buy closer to the live auction date of June 22, when more than 200 lots will be offered. There will also be an online auction, from June 16 to 23, of about 80 lots.

'The sale at Christie's this June offers a "through the keyhole" experience for fans across the globe to see and buy items from my mother's amazing Manhattan penthouse,' Melissa said in a statement. 'The auction celebrates her elegance and collecting style.'

Some of the pieces of for grabs include works of art like Dans L'Atelier, a painting by Edouard Vuillard created circa 1915, which is estimated to go for $120,000 to $180,000.

There is also a jeweled nephrite study of a Lily of the Valley leaf by Fabergé, estimated to sell for between $200,000 and $300,000. 

Some of the pieces are quite personal, too. One lot includes a silver Tiffany & Co. water bowl engraved with the words 'for Spike' (estimated to sell for $500 to $800), which was once used by Joan's beloved dog by the name. Spike appeared with his owner on the cover of People magazine before he died in 2001 at the age of 17.

Of course, it wouldn't be about the Fashion Police host if there wasn't actually plenty of fashion to go around.

Up for grabs will also be some 'spectacular' Bob Mackie gowns that Joan wore while headlining her stand-up show in Las Vegas, as well as several pieces of pricey jewelry.

Joan was a known glitz collector, and even published a book about it, Jewelry by Joan Rivers, in 1995. She also had her own jewelry collection for QVC — though the pieces that will be up for auction are a bit more expensive, from jewelers including Cartier, Van Cleef & Arpels, and Harry Winston.

'I've always loved jewelry,' she said in a QVC promo in 2009. 'My biggest wish is to be buried with more of it on than King Tut… Who I dated.’

The items are sure to fetch a pretty penny from collectors, art and fashion admirers, and Joan Rivers fans alike, but they'll also serve to help people in need.

Profits for the nonprofits: Melissa promised to honor her mother's generosity toward charitable causes

A portion of proceeds will benefit Guide Dogs for the Blind and God's Love We Deliver, a nonprofit that brings meals to home-bound people suffering from AIDS. Joan had volunteered often with God's Love We Deliver during her life, volunteering her time to deliver meals herself once a month.

'My mother's legacy as a much loved comedienne and philanthropist will be commemorated in this collaboration with Christie's and her generosity to charitable causes is something I will continue in her honor,' Melissa added.

When Joan passed, she left a portion of her $150 million fortune to both of those charities, as well as the Jewish Guild for the Blind, the Simon Wiesenthal Center, the Cystic Fibrosis Foundation, and the Jewish Home and Hospital Foundation.
