John Lennon's eldest son Julian is selling several pieces of music history from his personal collection.
However, he will keep the physical items as each piece of memorabilia will be sold as a non-fungible token (NFT).
Items being auctioned include a black cape worn by his father in the film Help! and handwritten notes for The Beatles song Hey Jude.
NFTs have been touted as the digital answer to collectables, but critics have warned about risks in the market.
