Prince’s unheard demo tape, containing three unreleased songs, his engagement ring and other prized possessions related to the musician are being auctioned off online.

The items being sold are courtesy of his first wife Mayte Garcia, former manager Owen Husney and collaborator/guitarist Dez Dickinson, Billboard reports. They include a cassette tape recorded in the 1970s, which contains three unreleased songs and earlier versions of “So Blue,” “Gotta Broken Heart Again” and “Sometimes It Snows in April.” The minimum bid for the tape is $20,000. It’s up for auction for another two days.

Fans can purchase his engagement ring for a minimum of $100,000. Other items up for sale include the musician’s previously worn stage outfits, including his velvet sequined jacket, and his five-piece set of wedding china with his famous “Love” symbol design.
