The Beatles signed 1970 letter valued at $75,000

A thank-you letter signed by all four members of The Beatles has been valued at up to $75,000. The letter was written in 1970, approximately three and a half months before the band officially broke up, a detail that significantly increased its appraisal value.

The item was featured on Antiques Roadshow, held by the son of a former Capitol Records executive. The letter is part of an Apple Records promotional set. Experts noted the rarity of a document signed by all four members dated from 1970.
