Joan Rivers' daughter, Melissa, gave ET a look at the memorabilia that meant so much to her late mother, which is now up for auction.
"My mother was a maximalist, which means she had a lot of stuff," Melissa joked with ET's Jennifer Peros.
The collection, available at Christie's in New York City until June 23, includes jewelry, furniture and gowns like the ruffled Oscar de la Renta cape dress she wore to the 1990 Tony Awards. The dramatic number is going for $1,200-$1,800.
Melissa hand-selected hundreds of items to sell over the next week, but there were a few things she couldn't let go.
"I kept everything that was on her night table," Melissa admitted.
While Joan always wanted to share her belongings, it was no easy task for Melissa to parcel through the items, which her mother took decades to amass.
"She never saw a tag sale or antique shop or auction where she couldn't find something at!" Melissa remembered fondly.
Despite her flair for collecting assets, Joan also had a talent for giving. Peros shared a personal story about Joan's generosity.
"I once said to her, 'I love your earrings,' and she took them off her ears and handed them to me," Peros recalled.
"Because they were from her QVC line," Melissa said.
Partial proceeds from the auction will go to charity.
