A collection of every single song to make it to the top of the singles chart has failed to sell at auction.
The huge collection, which includes more than 2,000 items, did not make the asking price of at least £25,000, so the owner decided not to sell it.
But the 35-year-old man from Brighton is hopeful he will still be able to sell the songs to a private collector.
Before the auction he said he wanted the collection to be continued or bought by a museum.
The first UK number one single, Italian-American singer Al Martino's Hear in My Heart, was bought by the owner's granddad in 1952.
The tunes are recorded on lots of different formats, and includes downloads, CD singles, DVD singles, cassette singles and vinyl records.
At the same auction the guitar which Sir Paul McCartney learned his first chords on was sold for £330,000.
The instrument was sold by a friend of the ex-Beatle, who said he would use the cash for his retirement.
