A pink javelin signed by Jessica Ennis, a large London2012 Royal Mail stamp autographed by Mo Farah and a Mary Poppins costume from the Olympic opening ceremony are going under the hammer today at an auction in Coventry.
London 2012 chairman Lord Coe described it as a chance for people "to own a unique piece of the Games".
Lord Coe received a special award at Buckingham Palace today for his role as chairman of London 2012.
The two-time Olympic champion was made a member of the Order of the Companions of Honour by the Princess Royal during an investiture ceremony.
He said: "It's a lovely honour and I'm deeply flattered.
It is really a recognition for the extraordinary work of so many people: our teams at Locog, the most talented, focused people I've ever worked with - and the people of Britain whose generosity of spirit helped get us across the line."
The Order consists of the sovereign and 65 ordinary members and recognises service of national importance.
Previous recipients include scientist Professor Stephen Hawking, naturalist Sir David Attenborough and painter David Hockney.
