Over 800 items owned by Ringo Starr and wife, Barbara Bach are going to auction at the end of the year.

The unprecedented number of Beatles-owned items will be offered December 4-5 at Julien’s Auctions in Beverly Hills.

Starr, 75, says he got the idea after the Grammy Museum asked to do an exhibition about his life in music in 2013-14.

Then another project, an upcoming book and exhibition currently at London’s National Portrait Gallery of photos Ringo took of his former mates, turned up ”boxes of negatives from the ’60s onward.”

Like his book, ”Photograph by Ringo Starr,” coming out later this month, a portion of the proceeds will benefit the couple’s Lotus Children Foundation that focuses on social welfare issues around the world.

Among the items that’ll go on the block, Ringo’s three-piece drum kit used in over 200 performances and a Rickenbacker guitar known as the ”Beatle-Backer” that John Lennon gave to Ringo.

Julien’s figures the sale could fetch between $5-million to $10-million.
