Rare Beatles memorabilia to go under the hammer in Auckland on Sunday

Rare and personal Beatles memorabilia will go under the hammer in Auckland on Sunday after a vendor with a remarkable story paid a visit to Webb's auction house. 

The British-born woman - who is letting her collection speak for itself - was once a secretary to the financial controller at the Beatles' company - Apple Corps.

The collection is a variety of carefully-kept mementoes of a secretary who worked with the Beatles in the 60s and didn't think her 'keepsakes' would be worth much to anyone else. 

"I was privileged enough to let her know that what she had was going to be worth tens of thousands of dollars," Webb's director of decorative arts Ben Erren told Newshub.

Among the items, she kept a company policy and procedures manual, an Apple Corp watch, her diary which included notes on Paul McCartney's housekeeper and John Lennon's holiday as well as royalty sheets for Beatles songs and some very special personal messages. 

Erren said included in the collection was a handwritten letter from one of the band members.

"There's a letter to the vendor from John Lennon handwritten, saying if she ever needed anything, hoping she was well, love from John and Yoko, and then hand-signed at the bottom."

The other remarkable and most valuable item is a handful of individual expense sheets from each Beatle. 

"Miscellaneous entertainment expenses which who knows what that could possibly be in the 60s with the Beatles! I took them straight to our finance department and said 'look, even the Beatles in the 60s had to do their expense sheets!'" Erren exclaimed.

The items are being sold in separate lots on Sunday morning and are expected to fetch more than $20,000 altogether. 

The current owner, who was shocked at the valuation, just wants to find a special home for some very special memories. 

Erren thought it was astonishing that one of the biggest names in music history took the time for someone who was their secretary.

"How cool is that, how humbling is that? That the biggest band in the world had all the time in the world for someone who was moving around their engagements."

The world-renowned rockers were also just her friends - George, Ringo, Paul, and John.
