The 1962 ten-inch pressing of songs "Till There Was You" and "Hello Little Girl" is adorned with the handwriting of their manager Brian Epstein who branded it a work of 'Paul McCartney & The Beatles' despite the latter track being considered the first song ever written by John Lennon.
The record was the first disc to be pressed before the Fab Four rose to prominence in 1962.
The person who unearthed the record is Les Maguire, former keyboardist of fellow Liverpool favourites Gerry and the Pacemakers. He referred to the discovery as the record "that sparked The Beatles' success."
Describing it as a "one-off," Maguire, 74, revealed that the item was given to him by Epstein in 1963 after its producer George Martin had returned it.
The record is expected to sell for over £10,000, however, Ian Shirley - editor of Record Collector Rare Record Price Guide - stated the item will "fascinate Beatles collectors worldwide," so there's no knowing how much it will fetch.
"It's no good to me so I've given it to my granddaughter, who is hoping to buy a house after passing her accountancy exams. I hope it goes for a good price."
The auction will take place at Warrington's Omega Auctions on 22 March; it'll be broadcast live to account for worldwide bidding.
