Also up for auction: a Platinum record plaque for Neverminda Gold record plaque for In Utero, and a lock of Kurt Cobain's hair.

According to Julien's Live, the lock of hair was given to doll maker and comic artist Dame Darcy by Courtney Love.

In a comic book style letter of authenticity, Darcy explains that in the 1990s she sold her handmade dolls in the back of her comic book Meat Cake. Love became a client and commissioned a doll for her daughter Frances using Cobain’s hair. This lock was the hair that remained once the doll was made. Accompanied by both a black and white and inked copy of the letter of authenticity."

Bidding for Cobain's hair starts at $4,000.
