Get the Best Foreign Currency Exchange Rates in 2026
Posted by: Ian Stainton • 10 Jun 2026
The best foreign currency exchange rate isn't just the highest-looking number on a board. It's the rate that gives you the most value after fees, spread, minimums, and the simple question of whether the provider will accept all your money, including coins, old notes, and withdrawn currency.
If you've just come home with a handful of euros, a few US dollars, some odd coins from a stopover, and one note that may not even still be in circulation, you've run into a practical problem most exchange guides skip. Getting the best outcome isn't only about timing the market. It's about finding a service that can convert what you have.
How to Get the Best Foreign Currency Exchange Rates
Leftover holiday money usually looks nothing like the neat examples in travel guides. It's mixed. It's incomplete. It often includes coins, small notes, and older currency that a bank cashier will reject without much explanation.
That's why the phrase best foreign currency exchange rates can be misleading. For many, the best deal is not the provider with the flashiest headline quote. It's the one that gives the strongest net result for the money in your hand.
What best really means
A useful way to judge an exchange offer is to ask four simple questions:
- What benchmark is it being compared with? In the UK, the most relevant neutral benchmark is the interbank or mid-market rate, before any provider margin or fee is added, as explained in Western Union's guide to comparing exchange rates and fees.
- What fees are added on top? A rate can look fine until a handling fee or minimum exchange rule cuts the value.
- What types of currency are accepted? Notes are one thing. Coins and withdrawn currency are another.
- What do you receive at the end? The right comparison is the final payout, not the marketing line.
Practical rule: If a provider won't take part of your leftover money, its “best rate” may be irrelevant.
A simple way to compare offers
Use this checklist before you exchange leftover currency:
Check the benchmark first
Compare the offer against a neutral market reference, not against another retailer's advert.Look at the full cost
Include fees, rate margin, minimum exchange amounts, and any payment restrictions.Check acceptance rules
Ask whether they accept current notes, coins, and old or withdrawn banknotes.Think in total value, not just rate
If one service takes only notes and another takes notes plus coins, the second may leave you with more money overall.Don't assume coins are worthless
They're often just inconvenient for mainstream providers, not valueless.
That last point matters more than commonly realised. Traditional travel money counters are built for common notes in active circulation. They're not designed for jars of mixed change, pre-euro currency, or old notes found in drawers years later.
What Really Determines Your Exchange Rate
Exchange rates feel mysterious until you separate the market price from the customer price. Once you do that, most of the confusion disappears.
The mid-market rate and the customer rate
Think of the mid-market rate as the wholesale price. It's the base value used to price a currency pair before a provider adds its own margin or fee. For UK comparisons, that's the technically relevant benchmark, and guidance aimed at UK users says you should compare both the published rate and the fees rather than looking at headline rates alone, because the final value depends on the spread and the fee structure, as noted in Western Union's explanation of the interbank and mid-market rate.
The rate you're offered as a customer is more like the retail price. It reflects the provider's costs, risk, and profit margin.
What the spread means in plain English
The spread is the gap between the market benchmark and the rate offered to you.
If that sounds technical, use the shop analogy. A shop buys stock at one price and sells it at another. Currency providers do something similar. The gap helps cover overheads and market movement.
That doesn't automatically make a spread unfair. The issue is whether the full offer remains sensible once everything is added up.
The four things that shape your final outcome
Market benchmark
This is the base level before retail markups.Provider spread
Different firms build in different margins.Extra fees
Handling charges, service fees, or minimum transaction rules can change the result fast.Timing
Rates move during the day, so the quote can change even before you decide.
For readers who want a plain-English breakdown of these moving parts, this guide on what determines currency exchange rates is a helpful primer.
A strong-looking exchange rate can still produce a weak payout if the fee structure is doing the real damage.
Why this matters more for leftover travel money
With holiday leftovers, small amounts can make pricing less efficient. A modest pile of notes might still be easy to exchange. A mixed bag of coins and outdated notes is harder to process, so many providers refuse it.
That's why “best rate” and “best overall outcome” are not always the same thing.
Where to Exchange Currency A Comparison
A lot of people start by asking where they can exchange foreign currency in the UK, then discover that each option has blind spots. One provider may be convenient but expensive. Another may offer better rates for standard notes but won't touch coins. Another may be fine for euros and dollars but not less common or withdrawn currency.
UK-facing guidance from Wise and Bankrate notes that banks and online providers often beat airport kiosks, but it also warns that rate markups, ATM charges, and minimum exchange amounts can materially affect the final value received, especially for small balances and less common currencies, as outlined in Wise's guide to avoiding huge exchange fees.
Comparison of UK Currency Exchange Options
| Exchange Option | Accepts Current Notes | Accepts Foreign Coins | Accepts Old/Withdrawn Currency | Typical Spread |
|---|---|---|---|---|
| High street bank | Usually sometimes limited by currency and account status | Rarely | Rarely | Often moderate, but varies and may include fees |
| Post Office or travel money counter | Usually for common currencies | Usually no | Usually no | Varies by branch and product |
| Airport kiosk | Usually for common travel currencies | Sometimes limited | Usually no | Often less favourable once margin and fees are considered |
| Specialist online service | Often yes, including wider acceptance rules | Often yes | Often yes | Varies by provider, so net payout matters most |
Why banks and bureaus say no
Banks and bureau counters usually focus on current, standardised banknotes because those are easier to verify, count, store, and resell. Coins are heavier, slower to process, and harder to redistribute. Withdrawn and obsolete money creates another layer of admin because it may need specialist valuation and handling.
That's not a judgement on whether the currency has value. It's a judgement on whether the provider's business model is built to deal with it.
Which option suits which situation
For current holiday notes only
A bank, bureau, or online platform may all be worth comparing.For small leftovers
Minimums and fees matter more than the headline rate.For mixed coins and notes
Specialist services tend to be the practical route.For old or withdrawn currency
You'll usually need a provider set up to handle non-standard money.
A useful starting point is this foreign currency exchange comparison, which focuses on the differences mainstream options often hide.
If one provider offers a better rate on paper but rejects half your bundle, it hasn't offered you a better deal.
How to Exchange Foreign Coins and Notes Online
Sending currency by post sounds unusual the first time you hear about it, but for leftover foreign money it's often the simplest route. It works especially well when the collection is messy. Mixed coins, assorted notes, and older currency are exactly the kinds of items online specialist services are built to process.
Step 1 Get your quote
Start by identifying what you have. Some services let you enter the currency type manually. Others provide a weight-based tool, which is useful if your change is unsorted and you don't want to separate every coin.
At this stage, check three things carefully:
Accepted currency types
Notes, coins, old notes, pre-euro issues, and discontinued currency are not always treated the same.Quoted value
Make sure the rate is shown before you commit.Payment method
Check whether payment is made by bank transfer, PayPal, or another option.
Step 2 Pack and send your currency
Once you accept the quote, package the money securely and send it using the provider's instructions. Specialist services notably differ from standard travel money counters; instead of asking you to arrive in person with neat stacks of current notes, they're built for mailed-in collections.
For example, exchange foreign coins and notes through a service that accepts mixed, withdrawn, and obsolete currency by post, verifies the contents, and then pays out after processing.
Step 3 Verification and payment
After the currency arrives, the provider checks what was sent, confirms the amount, and issues payment according to its stated process. According to the publisher information for this article, payment is issued within five working days after verification, and customers can choose PayPal or bank transfer.
Why this method works for awkward leftovers
Online exchange is often the easiest answer when your money doesn't fit the normal retail pattern.
- No need to sort every coin if the service supports mixed collections.
- No branch visit if everything is handled by post.
- No dead end for old notes if the provider accepts withdrawn currency.
- No wasted leftovers if even small or unusual holdings can be processed.
That combination is what turns a drawer full of leftover travel money into something usable.
Common Currency Exchange Mistakes and How to Avoid Them
People usually lose value in currency exchange through small assumptions, not big disasters. A poor decision at the airport, a fee you didn't notice, or a bag of coins left sitting in a kitchen drawer can all chip away at the return.
Mistake one only looking at the headline rate
A board can advertise an attractive figure while the actual value is reduced by fees, spread, or minimum transaction rules.
Avoid it: Compare the full payout, not just the top-line quote.
Mistake two assuming banks accept everything
Many people walk into a bank with leftover foreign coins and discover the answer is no. The same often applies to old or withdrawn notes.
Avoid it: Check acceptance rules first, especially if your currency is mixed or older.
Mistake three waiting until the airport
Airport counters solve an urgent problem, which is exactly why they're often a poor place to compare calmly. Convenience can cost you.
Avoid it: Sort out your exchange after the trip when you have time to compare proper options.
Mistake four treating coins as worthless
Coins aren't usually worthless. They're often just inconvenient for mainstream providers.
Avoid it: If you want to exchange foreign coins or exchange leftover currency, look for a specialist route rather than assuming the money has no use.
Mistake five breaking the process into lots of small exchanges
Small repeated exchanges can be inefficient, especially if a provider uses minimums or fixed handling charges.
Avoid it: Group your leftovers together and compare the total return.
Small fees matter more when the balance is small. That's why leftover holiday money needs a different kind of comparison.
Donating Leftover Foreign Currency to Charity
Not every pile of leftover travel money needs to become spending cash again. Sometimes the better option is to turn it into a donation.
That's especially true for the odd bits people tend to keep for years. A few coins from one trip, a note from another, and older currency that no longer fits any ordinary exchange desk can still be useful when collected and processed together.
Why old money can still help
For UK valuation work, the Bank of England's historical exchange-rate data goes back to January 1963, which allows even old and pre-euro currencies to be benchmarked against a long-run official reference rather than being treated as meaningless leftovers, as explained in the ICAEW guide to current and historical exchange rates.
That matters for charities. It means obsolete or withdrawn money doesn't automatically belong in a souvenir tin or the bin. With the right specialist handling, it can still be converted into meaningful value.
When donation makes sense
Donating is often a good fit when:
- You don't need the cash personally
- The amount is small and awkward
- You've got a mixed batch from several countries
- You'd rather clear the clutter and do something useful with it
Charities, supermarkets, airports, and other organisations often collect foreign coins and notes for this reason. Small individual leftovers may feel minor, but pooled together they become far more useful.
A simple alternative to letting it gather dust
If you've got a jar of old francs, pesetas, cents, or assorted coins from family holidays, donating can be the cleanest answer. It gives the money a purpose without requiring you to chase the perfect travel-money quote.
That's why many people choose to donate foreign coins to charity rather than leave them forgotten for another year.
Your Currency Exchange Questions Answered
Can you exchange foreign coins in the UK
Yes, but usually not through the places people try first. High street banks and standard travel money counters often focus on current banknotes. If you want to exchange foreign coins, you'll usually need a specialist service.
Do banks accept foreign coins and notes
Banks may accept some current foreign banknotes, but policies vary. Foreign coins are commonly refused, and old or withdrawn currency is often outside their normal process. That's one reason so much leftover foreign currency ends up sitting unused at home.
Does old or withdrawn foreign currency still have value
Sometimes, yes. Whether it can be converted depends on the currency, its status, and whether the service handling it is set up for older issues. Specialist platforms that deal with obsolete and withdrawn money can often assess currency that mainstream providers won't handle.
How do I know if I'm getting a fair rate
A fair rate is usually the one with the smallest deviation from the prevailing benchmark after accounting for explicit fees. For sterling-based benchmarking, neutral references such as the Bank of England's exchange-rate statistics and BIS bilateral exchange-rate data are used to understand underlying market levels, as explained in the BIS exchange-rate data resource.
In everyday terms, compare the final payout against a neutral benchmark and include all charges. Don't rely on the advertised rate alone.
What if my currency is mixed and unsorted
That's common. Mixed leftover holiday money is exactly why specialist services exist. Some use tools that let you estimate value without sorting every single coin by hand, which is far easier than trying to organise a random pile from several trips.
Is it safe to send currency by post
It can be, provided you follow the provider's packing and postage instructions carefully. Use the recommended method, package the contents securely, and keep records of what you sent. If you're using a specialist service, read its process and return policy before posting.
How long does payment take
According to the publisher information provided for this article, payment is issued within five working days after verification, using PayPal or bank transfer. Always check the provider's current terms before sending.
Can I exchange leftover currency instead of donating it
Yes. If you'd rather receive the value yourself, you can exchange leftover currency through a provider that accepts the types of money you hold. If the collection includes coins, mixed notes, or obsolete money, a specialist service is usually the practical option.
What's the easiest way to convert foreign coins and banknotes
The easiest route is an online specialist process: get a quote, pack the currency, send it, and receive payment after verification. That avoids the usual dead ends people hit at banks and bureau counters.
Is there any point keeping small amounts for my next trip
Sometimes, if you know you'll return soon and the currency is current and easy to use. But if the money has sat untouched for ages, or it's spread across multiple countries and includes coins or old notes, it's often better to convert it or donate it rather than let it go stale in a drawer.
If you want a practical way to exchange foreign coins, convert leftover notes, or deal with old and withdrawn currency that banks usually reject, We Buy All Currency offers a simple online route. You can check a quote, send mixed currency by post, and turn unused travel money into cash or a charity donation without needing to sort every coin first.
