Leftover foreign currency: what to do with it

Summer holiday season is upon us, which means many of us will be planning the big annual getaway to the sun. A major consideration when travelling overseas is always how much money to change up – after all, you don’t want to be left with useless foreign currency when you’re back.

Visa Europe estimates that most of us come home from our holidays with around £30 in unused cash, which many of us stick in a jar and forget all about it. Do that every year and you could soon have hundreds of pounds worth of useless cash lying around. The Daily Telegraph cites research from Zopa which states Brits have on average £110 lying around, which equates to around £2.9bn of discarded currency across the country.
