The auction received hundreds of bids as people supported the cause, driving the price from its starting bid of £50 and surpassing its recommended retail price of £1,795 within twelve hours of launch.
The auction frenzy comes hot on the heels of the huge Cumber-fan interest in the April issue of High Life which featured the Sherlock star. The magazines have been selling on eBay for £50 and mentions of the story occurred every eight minutes on social media at the peak of the hype.
High Life's editor, Kerry Smith said: "All the buzz around Benedict's British Airways' High Life shoot has prompted some very wild guesses about how much the coat would go for, but £5010 is way beyond our expectations. We're delighted it's raised so much money – it will really make a difference to Flying Start and the children they work with."
Flying Start is a global charity partnership between British Airways and Comic Relief, aiming to raise money to help children living disadvantaged lives in the UK and around the world.
