21-year-old Australian fan Dimitry Telfer won a piece of plastic celery worn in the series by Peter Davison - and autographed by the actor - in an eBay auction raising funds for Children in Need.
Telfer's winning bid was 5,500 pounds. The BBC put the signed celery stick up for auction in aid of the children's charity last week, with bidding starting at just 99p.
Dimity told Britain's Daily Mirror newspaper: "I couldn't let an opportunity like that get away from me and it's for a great cause. I got into 'Doctor Who' in 2005 and I've been hooked. Peter Davison is my favourite."
