Over 500 of the late broadcaster's iconic possessions will be available to purchase in order to raise money for his favoured charities.
The collection will include his famous Jim'll Fix It chair, which is valued at £8,000 to £12,000.
His £90,000 Rolls-Royce, a gold and diamond encrusted Rolex watch and the last of his Cuban cigars will also go under the hammer.
Savile, who was famed for his charity work, left over £5 million to two separate charitable funds in his will last year.
One of his final wishes was reportedly to sell the rest of his possessions in order to raise as much money as possible.
Other lots include his iconic Top of the Pops outfits, including the Superman T-shirt he wore while meeting Prince Charles.
There will also be a wide variety of medals, vests and multi-coloured tracksuits for sale.
The Jim'll Fix It chair comes with an ashtray inside one arm, along with two buttons on the other which operates trays carrying the medals, and another that produced his cup of tea.
The 550 lots will go to the Sir Jimmy Charitable Trust, which supports his various charities. It is expected to raise between £200,000 to £300,000.
The auction will take place at Saviles Hall by Dreweatts Bloomsbury in Leeds on July 30.
Sir Jimmy Savile died aged 84 in October 2011.
