The UK Has Millions in Unused Foreign Currency – Here’s What to Do With It

Posted by: Ian Stainton • 13 Apr 2026

Across the UK, millions of households are sitting on a hidden source of value – leftover foreign currency.

From spare euros and US dollars to forgotten coins from long-past holidays, this money often ends up in drawers, jars, and travel wallets. The surprising reality is that a significant proportion of this currency is never exchanged back into pounds.

So what’s causing this, and more importantly, what can you do about it?

Quick Answer: What should you do with leftover foreign currency?

You can convert leftover foreign coins and banknotes into cash using specialist services that accept:

Coins
Banknotes
Withdrawn currency
Mixed denominations

👉 The easiest way is to use a service that allows you to exchange foreign coins and notes online.

Why so much foreign currency goes unused

There are a few key reasons why people hold onto foreign money:

Reason	Explanation
Small amounts	Not worth exchanging at airports
Coins	Banks and bureaus don’t accept them
Forgotten travel money	Left in drawers after holidays
Old currency	People assume it’s no longer valid

Over time, these small amounts accumulate — often unnoticed.

The biggest issue: foreign coins

Coins are the most common form of leftover currency — and the hardest to exchange.

Why coins are a problem:

Most banks refuse them
Exchange bureaus don’t accept them
They are costly to process
They have low individual value

👉 This leaves millions of pounds worth of coins effectively out of circulation.

How much unused currency do UK households have?

While exact figures vary, industry estimates suggest:

Millions of pounds in coins remain unexchanged each year
The average household may hold £10–£50 in leftover currency
Frequent travellers often accumulate significantly more

Typical household breakdown:

Type of Currency	Likelihood
Euro coins	Very common
US Dollar notes	Common
Mixed currencies	Very common
Old / withdrawn currency	Often overlooked

What about old or withdrawn currency?

Many people also hold currency that is no longer in active circulation, including:

Pre-Euro currencies (e.g. French Francs, German Marks)
Older banknote series
Withdrawn or replaced notes

Although banks often refuse these, they may still hold exchange value through specialist providers.

How to turn leftover currency into cash

The process is now far easier than most people expect:

Add your coins and banknotes to an online account
Send your currency securely
Receive payment directly to your bank

👉 This removes the need to visit banks or exchange counters.

Who benefits most from exchanging leftover currency?

This isn’t just for holidaymakers — a wide range of people benefit:

Households clearing out drawers or storage
Charities receiving international donations
Businesses handling foreign cash
Frequent travellers

Why people are switching to specialist exchange services

Traditional options are limited — but specialist services are designed for this exact problem.

Key advantages:

Accept coins (unlike banks)
Accept withdrawn currency
Handle mixed denominations
Simple online process
UK-based service

👉 This makes them the most practical solution for unused currency.

Common mistakes people make

Avoid these common pitfalls:

Leaving currency unused for years
Throwing coins away
Assuming small amounts aren’t worth anything
Trying to exchange coins at banks

👉 Even small amounts can add up when combined.

Is it worth exchanging small amounts?

Yes — especially when combined.

Example:

Scenario	Estimated Value
Single trip coins	£5–£15
Multiple trips combined	£20–£50+
Bulk mixed currency	£50+

👉 What looks insignificant individually can become valuable in total.
