Gathering dust in the deep recesses of your cupboard could be a classic toy that today could be worth thousands.
You may have spent several weeks' pocket money on a Tamagotchi that you soon abandoned after becoming frustrated with it; those 1990s virtual pets were jolly hard to keep alive.
But your £11 could have been well spent as a functioning Tamagotchi can fetch up to £3,000, according to a survey by Sunny Loans.
Perhaps your original 1970s edition of Hungry Hippos is sitting in pristine condition in your attic after your sibling refused to play with you anymore because you kept crying when you lost.
And it's not just toys from the pre-internet days that fetch a pretty penny; collectibles such as Japanese Beyblades - then worth £6 - can sell for £130.
Just make sure you keep the original packaging.
