A passport belonging to late music legend Marvin Gaye has been discovered during an episode of TV hit Antiques Roadshow. The rare piece of memorabilia was appraised on the U.S. version of the long-running British TV programme and given an estimated value of around $20,000 (£12,500). The passport, which was issued to the singer in 1964, was found by a fan who bought a stack of records from an estate sale following the death of a Motown musician. The unnamed owner said of the discovery, which cost him just 50 cents (31 pence), "When I got home, I was going through them (the records) and out of an album fell this passport. So it literally fell into my hands." Gaye died in 1984.
