The butter dish fetched three times the estimated price
A silver butter dish used as an ashtray by Sir Winston Churchill has fetched £4,200 at auction in Norfolk.
Experts expected the shell-shaped dish to sell for at least £1,500 when it went under the hammer at Keys Auctions in Aylsham.
Sales staff said the dish attracted interest from around the world.
The auctioneers said Churchill flicked cigar ash into the 200-year-old dish when at a political dining club which met in the Savoy Hotel in London.
Churchill helped found The Other Club in 1911 and last dined there in December 1964 - six weeks before his death.
The buyer of the ashtray, who is a UK-based private collector, wished to remain anonymous, William King from Keys said.
Mr King added: "It's just purely the provenance that added the value to it, so at the end of the day £4,200 for what is a butter dish is a very good price."
He said an old Chesterfield sofa from Churchill's Whitehall office that was destined for the skip made £7,500 at auction recently. The estimate had been £40.
