The auction by Sotheby's will also include works by Andy Warhol, Damien Hirst, David Bailey and other prominent artists collected by Hall, ex-wife of Rolling Stone Mick Jagger.
The auction house said Monday the works will be sold on Oct. 15-16 as part of a larger contemporary art sale.
Sotheby's says the Lucian Freud portrait called "Eight Months Gone" is the centerpiece of the auction and is expected to fetch more than 300,000 pounds ($460,000).
The collection also includes two other works by Freud, often acclaimed as one of the world's greatest living painters.
