John F Kennedy's personal rosary beads and crucifix will be sold by RR Auction this autumn, joined by his assassin Lee Harvey Oswald's wedding band.
The rosary beads have been described by the auction house as "arguably the most personal possession associated with John F Kennedy ever offered at public auction".
RR Auction's vice president Bobby Livingston is reported by WCVB.com as saying that the beads could bring upwards of $1m.
The beads were gifted to Kennedy's best friend and personal assistant David F Powers, whose remarkable collection of JFK memorabilia sold at John McInnis Auctions in February.
Meanwhile, Lee Harvey Oswald's wedding ring, which was consigned by his ex-wife Marina Oswald Porter, could see up to $100,000 depending on interest.
According to Porter, Oswald visited her the day before Kennedy's shooting in an attempt to reconcile their broken marriage.
He left his ring, which is stamped with a hammer and sickle motif (the pair were married in Russia), and money from his pockets at her house.
Paul Fraser Collectibles has a superb selection of JFK memorabilia for sale, including authentic strands of his hair and rare autographed photos.
