Joan Rivers isn't done contributing to the world just yet - the comedian's private collection of artwork, gems, jewelry, and clothing from her Manhattan penthouse will be auctioned off this June, with part of the proceeds donated to two beloved charities.

Over 200 pieces of glamorous couture will be sold in a live auction in New York June 22, and another 80 pieces in a tandem online auction during that week. The two charities benefiting are God's Love We Deliver-a delivery service for the ill operating in New York-and Guide Dogs For The Blind.

The auctions will be hosted by Christie's, which has estimated the pieces in this collection to earn anywhere from $500 to $200,000 apiece.

"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," Joan's daughter Melissa announced in a press release.

Hollywood glamour will mingle among the decorative Fabergé art, paintings, and fine French furniture: a series of spectacular Bob Mackie gowns from her Las Vegas headliner years is sure to be a fan favorite.

Known as an animal lover, the most fun piece in the collection might be the Tiffany silver water bowl made for Joan's beloved dog, engraved with the words, "for Spike".
