Sharon and Ozzy Osbourne have managed to raise a massive from $800,000 from their 'garage sale'.

Raising funds for the Sharon Osbourne Colon Cancer Foundation, the Osbournes sold off many items of rock memorabilia, as well as furniture and knick-knacks from their Berverly Hills mansion made famous on their hit MTV reality show.

Auction manager Darren Julien said, "The Osbourne factor more than doubled the value of some items," adding the couple's broad fanbase was, "unlike anything we have ever seen by record numbers of bidder registrations."
