From mugs to Marmite, these items could make you a fortune in the future

Lottery wins, promotions and side hustles are all well and good when it comes to making a little extra money – but according to new research from Gumtree, you could already be growing a nest egg at home without even realising it.

The buying and selling community asked Tracy Martin, an expert in 21st Century Collectables, to list the most valuable items that have been produced in recent years, and predict how much they might be worth in the future. And it’s good news if you’ve been buying Radley handbags, Pandora charms or Emma Bridgewater mugs…

Commenting on her round-up, Tracy explained: ‘Many of the items might already be in your home, attic or are easily found online, so it’s time to get searching for those unassuming gems as they could be worth a small fortune in future. Statement pieces or items typical of the era likely to evoke nostalgia in years to come are often the safest bets.’

So, are you sitting on a surprise pot of gold? Here are the items that Tracey says you should keep hold of – for now, at least.

Tracy’s tips for first time collectors

1. Buy into reputable brands – a designer name or well-known manufacturer will always stand the test of time

2. Go for quality over quantity – investing in quality pieces is a good start as these are more likely to increase in value

3. Tap into nostalgia – search for items which represent the era in which we’re living in. Memories play a big part in making something appealing, especially when it comes to toys and games

4. Maintain mint condition as much as possible – store possessions safely to avoid unnecessary damage. Keep original packaging – and ideally paperwork and receipts showing original price paid – as being able to prove provenance will only add value

5. Hunt down items from your home – sites like Gumtree offer a great way to simply search for items without having to spend time trawling vintage and charity shops. Use key words such as ‘original’ and ‘limited edition’ and you could find a winner right on your doorstep

6. Buy it because you love it – this is my fundamental rule of thumb. Never buy an item if it’s something that you cannot live with and gain enjoyment from. That way, if it increases in value, it’s a bonus.
