Are you sitting on an unused treasure trove of old mobile phones and gadgets – worth enough to pay for a weekend for two in Mallorca?

We've all got a dusty old phone or two sat in a drawer, abandoned when the latest upgrade came along.

Each person has at least one old mobile gathering dust in drawers that could be worth on average £55 if sold second hand, a new study by gadget and gaming shop CeX shows.

But not many people know of the treasures to be found around our own homes.

Hugh Man, co-founder and chairman at CeX said: “All the old phones, tech, consoles and discs we forget about, still have a lot of value. Most people have no idea they have literally little piles of treasure that have been sitting for years in their cupboards.”

The average old iPhone 5s can fetch up to £44 second hand and even the Nokia 3310 – which sold over 126 million worldwide – is worth a tenner.
