A Simple Guide to Foreign Currency Exchange Comparison
Posted by: Ian • 8 Aug 2025
Got a jar of leftover holiday money sitting on a shelf? If you're like most of us, you've come back from a trip abroad with a wallet full of foreign currency. While the banknotes might get used on the next trip, that clunky collection of coins often ends up forgotten in a drawer, gathering dust.

Finding the Best Way to Exchange Your Leftover Currency

Finding a place to exchange foreign coins and notes can feel like a mission in itself. Your local bank or the airport kiosk might seem like the obvious choice, but they often turn away coins and won't touch any currency that's become obsolete. This leaves you feeling like you have very few options.

How the UK Foreign Exchange Market Affects Your Wallet

When you’re looking to convert foreign coins and banknotes, it’s easy to think it’s just a simple transaction. But the actual value you get for that jar of leftover holiday money is directly connected to the massive, constantly shifting world of the foreign exchange (FX) market.
A little real-world insight into how this market works can make a world of difference in understanding why rates change so often and what a good deal really looks like.
At its heart, the FX market is a global marketplace where currencies are traded against one another, and London is one of its biggest players. The UK’s foreign exchange market is incredibly busy. To give you an idea, a recent report showed that in April 2025, the average daily turnover rocketed to a record $4.045 trillion. This massive jump was driven by global trade and market activity, as you can discover more about on the Bank of England's website.
This incredible volume of currency being bought and sold every second is what directly influences the exchange rates you’re offered.
Understanding Key Market Concepts
The exchange rates you see quoted are generally based on two main types of trades happening in this enormous market.
- Spot FX: This is the here-and-now exchange of one currency for another at the current market rate. If you check a "live" exchange rate online, you’re looking at the spot price. This part of the market is extremely fast-paced, recently growing by 42% to $1.293 trillion traded daily, which shows just how quickly rates can move.
- FX Swaps: These are slightly more complex. It's an agreement where two parties trade currencies for a fixed amount of time and then agree to swap them back later. FX swaps are the most traded instrument in the market, accounting for a staggering $1.563 trillion in daily volume.
These high-level financial trades are what set the rates that ultimately decide how many pounds your leftover euros, dollars, or yen are worth. A tiny shift in the market, sparked by economic news or a global event, can directly change the value of the currency sitting in your drawer.
Why This Matters for Your Exchange
This might all sound a bit distant when all you have is a handful of mixed coins, but it's the reason why finding the right exchange service is so important. When you use a company to exchange foreign coins and notes, that provider has to work within this complex and volatile market to offer you a rate.
Because the market is always moving, the rates offered by different exchange services can vary quite a bit. Some might update their rates constantly, while others might play it safe and offer less competitive figures to shield themselves from sudden market swings.
This is a critical part of any foreign currency exchange comparison. It’s not just about the fees, but about how closely and fairly a provider reflects the true market value of your currency.
Comparing Your Currency Exchange Options
So, you've got some leftover foreign currency from a trip. The question is, what's the best way to change it back? A proper foreign currency exchange comparison goes deeper than just the advertised rate. You need to think about convenience, hidden fees, and whether a place will even take the money you have.
Let's break down the usual suspects to see how they really compare. Your first thought might be the most obvious places, but as you'll see, they're often not the most practical or valuable choices. Each one has its place, but knowing their limits is the key to not getting short-changed.
High Street Banks and Post Offices
For most people, popping into the local high street bank or Post Office seems like the logical first step. They’re convenient, sure, especially if you just have some common banknotes like euros or US dollars. But that’s where the convenience often ends.
The biggest issue? They almost always refuse to exchange foreign coins. Their entire setup is geared towards paper money, leaving you stuck with that heavy jar of shrapnel. And if you're holding onto old, out-of-circulation currency – think pre-euro Spanish pesetas or French francs – you'll find they simply can't help.
The real problem with these traditional options is their rigidity. They are built for simple, high-volume banknote exchanges, not for the messy, mixed-up reality of leftover holiday money.
Airport Currency Kiosks
We've all seen them. Airport kiosks offer that last-minute convenience when you're rushing for a flight, but you pay a hefty price for it. The exchange rates are notoriously poor, and the fees can be far higher than you'd find anywhere else. Just like the banks, they have no interest in your leftover coins or any outdated currency you might have.
This infographic sheds some light on the economic forces, like interest and inflation rates, that shape the baseline exchange rates providers work from.

It shows how a country's economic health and government policies directly affect its currency's value, which ultimately determines the rate you're offered at the counter.

Currency Exchange Service Feature Comparison
To help you see the differences at a glance, we've put together a simple table comparing the key features of each option.
| Service Provider | Accepts Foreign Coins | Accepts Old/Obsolete Notes | Average Fees | Convenience Level | Best For |
|---|---|---|---|---|---|
| Specialist Online Service | Yes (unsorted) | Yes | Transparent, competitive rates | High (mail-in from home) | Mixed coins & old notes |
| High Street Bank | No | No | Moderate fees, fair rates | Medium (in-person visit) | Common, current banknotes |
| Post Office | No | No | Moderate fees, fair rates | Medium (in-person visit) | Common, current banknotes |

Ultimately, the best choice boils down to what you have. If you just have a few crisp, common banknotes, your bank might do the trick. But for the very common problem of a mixed bag of coins and old notes, our specialist service offers the only genuinely comprehensive and hassle-free solution.
Which Exchange Service Is Right for You

When it comes to getting rid of leftover travel money, making a smart foreign currency exchange comparison really comes down to what you have in your hands. There’s no single "best" service for everyone; it’s about finding the perfect match for the specific currency you’re holding.
To see what I mean, let’s walk through a few real-world situations. You'll quickly see why a specialist approach often gives you the most value with the least fuss, especially when you're dealing with money that most places turn away.
Scenario 1: Mixed Coins and Notes from a Family Holiday
This is probably the most common headache. You’ve just come back from a trip to Spain or France with a few euro banknotes and a pocketful of heavy coins. High street banks and the Post Office will gladly take the notes, but they’ll flat-out refuse to exchange foreign coins. You’re left with only half the job done.
Here, a specialist online service is the clear winner. We offer a fast, simple solution where you don’t even need to sort anything. Just send us the whole lot—notes and coins together—and we take care of it. Our process is 100% guaranteed, so you know you're getting value from every last cent.
Scenario 2: Discovering Old, Obsolete Currency
Picture this: you're clearing out a relative’s attic and stumble upon a stash of old Spanish pesetas, German deutschmarks, or even some old British shillings. These currencies aren't in circulation anymore. No bank, Post Office, or airport kiosk will touch them. To them, it's just worthless paper and metal.
This is where our service really shines. We specialise in exchanging obsolete and withdrawn currency from all over the world. What others see as scrap, we see as value just waiting to be unlocked.
We have the know-how to assess and convert foreign coins and banknotes that have been out of use for years. This unique service means you can turn a forgotten find into actual cash—something you just won't find on the high street. It's why we're trusted by major charities who often receive this kind of currency in donations.
Scenario 3: Donating Currency to a Good Cause
Maybe you have a small collection of leftover foreign currency and want to put it towards a cause you believe in. The problem is, taking small bags of mixed currency to a local charity shop is often more trouble than it's worth for them to process.
Our service provides a direct way to donate foreign coins to charity. Because we already work with major UK charities, you can send your currency straight to us, and we'll direct the full value to one of our partners. It’s a secure and efficient way to ensure your donation actually makes a difference, which is why we’re trusted by police forces and major supermarkets to handle currency responsibly.
For any of these scenarios, especially when you're dealing with mixed or old currency, our simple mail-in process is the most sensible choice. You can find out more and begin your currency exchange on our website.
Unlocking the Value in Old and Foreign Coins
That jar of foreign coins or those old banknotes you have tucked away in a drawer often feel more like clutter than cash. It’s a common story: you try to exchange them at a bank or Post Office, only to be told they can't help. This leads many to assume they're worthless, causing millions in potential cash to be lost every single year.
But here’s the truth: there's real, hidden value in what most places consider ‘unusable’ currency. The main reason traditional exchange providers turn away foreign coins or old, obsolete banknotes is simply down to their operations. Their systems are built for quick, easy deals with current paper money, which makes sorting and valuing a mixed bag of coins far too time-consuming and costly for them.
This is exactly where we come in. Our entire service is built around making it fast, easy, and completely hassle-free to convert foreign coins and banknotes of all kinds, from anywhere in the world.
Turning Clutter into Cash or Charity
We designed our service to be effortlessly simple for you. There’s absolutely no need to sort your coins or separate different currencies. You can pack it all up—from modern euro cents to pre-euro German deutschmarks—into a single parcel and send it off to us. It’s a straightforward way to turn a forgotten collection into real money.
What really sets us apart is our commitment to finding value where others won't even look. We are one of the very few places that will happily assess and pay for both withdrawn currency and mixed foreign shrapnel, backed by a 100% guaranteed service.
This also creates a powerful way to do some good. You can easily choose to donate foreign coins to charity through our platform. We have established, trusted partnerships with major UK charities that rely on us to turn these small, otherwise unusable donations into significant funds for their work. It's a responsibility we take very seriously, which is why we’re also trusted by police forces and major supermarkets. To see how you can unlock this potential, have a look at our guide on the value of your leftover foreign coins.
The value of these currencies is also tied to the bigger economic picture. For instance, UK trade figures constantly affect currency values. In the three months to May 2025, a trade deficit of £13.2 billion and different export trends between EU and non-EU countries sent ripples through the FX market, directly impacting GBP exchange rates. You can explore more about these UK trade dynamics on the ONS website. It just goes to show how even the smallest coins are part of a much larger global financial story.
Why Trust and Guarantees Are Non-Negotiable
When you’re looking to exchange foreign currency, it’s about so much more than just the rate. It’s about trust. After all, you’re sending your money away and need to be completely confident that you won’t be hit with surprise fees, lost funds, or a poor valuation. That’s why credibility and solid guarantees should be right at the top of your list.
A company’s reputation speaks volumes.
