The letter, explaining the singer's reasons for returning his royal medal, was discovered tucked away inside the sleeve of a record that was part of a collection picked up for just $14 two decades ago.
Julien's Auctions' upcoming Beatles and Rock 'n' Roll Discovery Day event at the Hard Rock Cafe will feature a treasure trove of Fab Four fare, with over 81,000 iconic pieces up for grabs. Highlights also include a collection of 26 negatives containing rare and never-before-seen photographs of John Lennon, taken in February, 1970.
Julien's Auctions directors will be hoping for a landmark day after breaking world records with the sale of Beatles' memorabilia, including Lennon's acoustic guitar, Ringo Starr's Ludwig drum kit and The Beatles' "White Album" which is owned by Starr.
The Discovery Day auction will take place on May 17.
