So if you've been thinking of decluttering your loft - or house - now may be the time to do it.
From Harry Potter books to Lego sets, you could be sitting on a fortune.
That's why storage expert Vlatka Lake has has revealed the old items you should look out for in your loft and how you can make the most out of your clutter.
The expert does say that you should keep an eye out for any first or original editions of any items, such as books and gaming consoles, as they will most likely fetch the highest prices on places such as Amazon and eBay.
Vlatka Lake at Space Station commented: "We all amass various belongings throughout our lives – they tell our stories and offer us a look back into the past in some instances. However, eventually these belongings can become more of a hinderance if we start to need more space around the home."
