Eight things lying around your house which could be worth a fortune

1) First generation iPod Potential value: £900

First generation iPods have changed hands for eye-watering sums – but only for one of the very first generation model, with black-and-white display and directional buttons, and even then only still in the original packaging. For a pristine first-gen 5Gb iPod, still in the packaging, buyers have paid up to £10,000 each – for a used one, you can expect around £700.
