As the new plastic £5 notes slip into circulation, old five pound notes might be worth holding onto.
An online antiques dealer, thesaleroom.com, says an old fiver could be worth as much as 140 times more in years to come.
Bank notes from 30 years ago are worth so much more now than they were back in the day, with a Bank of England £5 note dating from 1979 set to sell at auction for an estimated price of £7,000.
You could still make between £100 and £150 for a £5 note from 1990.
Old money isn’t the only kind to hang onto either! According to eBay, you can also make a decent profit from one of the new £5 notes.
If you have one of the first batch of notes, with serial numbers starting with AA01, you could have your hands on a collector’s item – and make around £200.
