Coins and Change: The 2026 Guide to Exchanging Foreign Money
Posted by: Ian Stainton • 5 May 2026
The best way to deal with foreign coins and change is to use a specialist online exchange service that accepts coins, notes, and old or withdrawn currency and lets you post it for payment to your bank or to a charity. That matters because so much money gets stranded in drawers, jars, glove boxes, charity tins, and shop back offices when traditional exchange routes won't touch mixed or obsolete currency.
You only realise there's a problem when you try to do something sensible with your leftover money. You come home from holiday with euros, dollars, and a few coins from somewhere you changed planes. Or you run a charity, attraction, or small business and keep collecting bits of foreign change that nobody on the high street wants.
That frustration is normal. The fix is simpler than commonly expected, especially if you stop thinking like a bank branch and start thinking like a specialist processor.
That Jar of Leftover Coins and Change Hiding in Your Home
A lot of coins and change don't look valuable because each piece feels small on its own. That's why people leave foreign money untouched for months, sometimes years. It sits in kitchen drawers, old travel wallets, bedside tins, and the bottom of suitcases until nobody remembers where it came from.
The scale of that habit is often underestimated. UK households are estimated to hold around £1–2 billion in unspent foreign coins and notes, and the average UK family reportedly loses the equivalent of £200–£300 per year in unused foreign currency according to research discussed by Webuyallcurrency.
The simplest answer
If you want the practical version, use a specialist service that accepts mixed currency and doesn't require you to separate every coin by country first. That's the route that usually saves the most time and causes the least friction.
A good process looks like this:
- Gather everything together: Include loose coins, notes, old travel wallets, and any withdrawn currency you weren't sure about.
- Check whether the service accepts mixed and obsolete money: This matters more than a headline rate.
- Send it once, not in batches: Consolidating a collection is usually easier than trying to solve each currency separately.
- Choose payment or donation: If you don't need the cash yourself, you can often exchange foreign coins into a charity payment instead.
Practical rule: If you're delaying because the pile looks too messy, that's usually the sign you need a specialist service, not more sorting trays.
Why this problem keeps growing
People assume they'll exchange the money on the next trip. In reality, they often add more to the same jar. Families do it after holidays. Students do it after time abroad. Retired travellers do it after years of short breaks and cruises. Businesses and charities do it because staff don't have time to process small-value mixed currency by hand.
The result is the same. Money that could be converted or donated ends up treated like clutter.
What You Can Exchange and Why Banks Often Say No
A traveller brings back a pouch of coins from three trips, a charity opens a donation box full of mixed foreign money, and a small business finds old notes in a drawer after years of overseas cash sales. All three are holding real value. All three often get the same answer from a bank branch: no.
The reason is usually operational, not personal. High street banks are set up for everyday banking. Travel money counters focus on current, common banknotes. Mixed coins, withdrawn notes, pre-euro currency, and older British or Irish denominations sit outside that model, even when the money itself is genuine.
Currency exchange options compared
| Currency Type | High Street Banks | Exchange Bureaus | Specialist Online Service |
|---|---|---|---|
| Current foreign banknotes | Sometimes accepted | Often accepted | Accepted |
| Foreign coins | Usually not accepted | Usually not accepted | Accepted |
| Mixed coins and notes | Rarely practical | Rarely practical | Accepted |
| Withdrawn foreign notes | Usually not accepted | Usually not accepted | Accepted |
| Pre-euro currency | Usually not accepted | Usually not accepted | Accepted |
| Old British and Irish coins | Usually not accepted | Not typical | Accepted |
| Unsorted collections | Usually not accepted | Usually not accepted | Accepted |
Why traditional providers reject coins and old currency
Coins create a handling problem. Staff have to count them, verify them, store them, and move them on in volumes that rarely justify the time. For a branch built around accounts, cash deposits, and standard note exchange, a bag of mixed foreign coins is slow work with limited resale value.
Withdrawn and obsolete money creates a different bottleneck. Someone has to identify the series, check whether it can still be exchanged, and decide whether it belongs in a standard banking process at all. Many front-counter teams are not trained or equipped for that kind of assessment.
That is why a genuine collection still gets turned away.
Banks and bureaus usually work well for straightforward travel money. They are a poor fit for collections that are mixed, old, coin-heavy, withdrawn, or gathered over time from multiple people.
What specialist processing changes
A specialist service is designed for the cases that standard providers avoid. That matters whether you are clearing out a jar at home, processing charity donations, or dealing with accumulated overseas cash in a business.
In practice, that means the service can handle:
- Foreign coins and notes together: useful if your leftover money is a mix rather than a tidy stack of notes
- Withdrawn and obsolete currency: including pre-euro money and older issues that banks often refuse
- Unsorted collections: helpful for anyone who does not want to sort every item by country before sending it
- Personal, charity, and business volumes: from small holiday leftovers to regular collection bags and back-office clear-outs
Tools also matter in this context. A clear online process for exchanging foreign coins and notes removes one of the biggest points of failure, which is the assumption that every currency type needs a different route. A specialist service can treat coins, notes, current issues, and withdrawn money as one job instead of four separate problems.
Your Step-by-Step Guide to Exchanging All Foreign Currency
The process is usually much easier once you stop trying to force everything through a bank branch. What works best is a single workflow that handles coins, notes, and withdrawn currency together.
Gather everything first
Start by pulling together all your leftover foreign currency in one place. Include recent holiday money, older notes, pre-euro coins, and anything you're unsure about. If you're acting for a charity or business, gather from all the usual collection points before you send anything.
Don't lose time trying to create perfect little piles unless a service specifically asks for it. In practice, unsorted collections are common, and specialist systems are designed around that reality.
Use the online quote or wizard
The most practical systems let you identify what you have without needing expert knowledge. If the service uses a weight-based wizard or similar tool, that's especially helpful for bags of mixed coins.
Behind the scenes, the processing logic matters. The coin change problem is commonly solved with dynamic programming at O(n*c) time complexity and O(n*c) space complexity, while a naive recursive approach can become impractical at scale, as explained in Simplilearn's overview of the coin change problem. For customers, the practical takeaway is simpler. Better processing logic means faster quote generation and less delay when someone sends a mixed collection.
Pack your currency securely
Use sturdy packaging. Coins are heavy, and weak envelopes split. Notes should be kept flat and dry. If you're sending multiple currencies, keep them contained so they don't spill or tear through the outer packaging in transit.
A few habits help:
- Use strong outer packaging: Coins can damage thin paper envelopes.
- Keep notes dry and straight: Moisture and folding can complicate handling.
- Include requested paperwork: This avoids delays matching your parcel to your quote.
- Double-check the sending instructions: Weight limits and packaging rules matter.
If you're sending a mixed collection, the safest parcel is usually the simplest one. Secure contents well, label clearly, and avoid overcomplicating the packing.
Verification is where trust is built
Once the currency arrives, proper verification matters. Industry data indicates that approximately 3-5% of submitted collections contain items outside acceptable exchange parameters, such as heavily damaged coins or non-currency tokens, and a two-stage verification process combining an algorithmic pre-screen with expert assessment helps protect customers while valuing legitimate obscure currencies correctly according to UpGrad's discussion of verification and classification.
That matters most with the messy real-world stuff. Old escudos, pesetas, lire, worn coins, unusual denominations, and items people aren't sure about all need more than a quick glance.
Receive payment or donate the value
After verification, payment is issued by bank transfer or another offered method. Some services also let you direct the proceeds to charity instead. For many people, that's the easiest way to turn forgotten travel money into something useful.
The most reassuring setup is one with clear rates shown up front, straightforward verification, and a return option if you don't want to proceed after the quote is confirmed.
Real-World Scenarios for Travellers Charities and Businesses
The easiest way to understand coins and change is to look at how different people deal with it. The problem looks different in a family kitchen, a charity office, and a business back room, but the practical solution is often the same.
A traveller with a mixed holiday stash
A traveller comes back from several trips with euros, US dollars, a few coins from Eastern Europe, and notes from a country they no longer visit. A bank may only want current notes, and even then only selected currencies. The coins stay at home because nobody local wants them.
A specialist route works better because it handles the collection as it is. Mixed, unsorted, and not especially tidy. That saves the customer from trying to split the pile into "possible" and "probably useless" categories.
A charity with buckets of donated foreign money
Charities often receive travel leftovers through collection tins, supporter campaigns, events, and public donation points. The money is valuable, but only if someone can convert it. UK attractions and charities often collect thousands of pounds' worth of foreign coins each year yet struggle to monetise it, and specialist exchange services provide a tax-efficient route to turn that waste currency into fundraising income. The source for that figure is used earlier in the article, and the practical point is simple. Specialist processing enables donations that might otherwise sit untouched.
For charities, the gain is operational. Staff and volunteers don't have to become currency experts. They can donate foreign coins to charity through a service built for that purpose.
A charity doesn't need more foreign coins. It needs a clean route from donation tin to usable funds.
A small business receiving foreign money in error
Tourist-facing shops, visitor attractions, transport businesses, and hospitality venues often end up with foreign coins and notes mixed into takings. Staff may accept them accidentally. Customers may leave them in tip jars or donation pots. Over time, the collection becomes too awkward to ignore and too irregular for the bank to help with.
For a business, the right answer is usually consistency. Keep a separate container for foreign cash, consolidate it periodically, and use one process every time. That keeps back-office handling simple and stops foreign currency from becoming permanent drawer clutter.
Common Mistakes to Avoid With Your Leftover Coins and Change
You get back from a trip, empty your pockets into a jar, and tell yourself you'll sort it later. Six months on, the jar is fuller, there are a few old notes in a drawer, and nobody is quite sure what is still usable. That is usually how value gets stranded.
Assuming airport exchange desks will take coins
Airport counters are built around current notes for active travellers. Mixed coins, small denominations, and older currency are often outside their process. Travellers regularly leave the airport with the same change they arrived with, plus a fresh reminder to deal with it later.
Treat the airport as the least reliable place to solve a coins problem. If you have coins, notes, and possibly withdrawn currency from more than one country, use one specialist route built to handle the lot together.
Throwing away old or withdrawn currency
This catches travellers, charities, and businesses alike. A coin is no longer spendable in shops, so it gets treated like a souvenir or scrap. Old Irish punt, pre-euro coins, discontinued notes, and obsolete foreign issues are the usual casualties.
Some withdrawn currency can still be exchanged through specialist handling even after banks decline it. Check first. Discarding it should be the last step, not the first.
Spending hours sorting every coin
Sorting can help, but over-sorting is one of the biggest time drains I see. People line up coins by country, denomination, and year, only to use a service that accepts mixed submissions anyway.
Do the minimum useful prep. Remove obvious non-currency items such as tokens, arcade pieces, and souvenir medallions. Keep notes separate from coins if asked. Beyond that, do not turn a simple clear-out into a weekend project.
If perfect sorting is the reason the job keeps getting delayed, the process is too fussy for the task.
Waiting until the collection becomes overwhelming
This is how a manageable amount turns into a box nobody wants to touch. At home, it sits in cupboards. In charities, it builds up in donation tins and back offices. In businesses, it gets pushed to the side of the cashing-up area until someone has to deal with a mixed pile from ten countries.
Set a simple threshold. Once the jar is full, once the office bag reaches a certain size, or once the shop has enough foreign cash to justify posting it, process it. Regular clearing is easier to verify, pack, and account for.
Forgetting damaged or odd items may be rejected
Mixed collections nearly always contain extras. Bent coins, corroded pieces, novelty tokens, washers, old transport tokens, and badly damaged notes all turn up. That does not ruin the whole batch, but it can affect what is accepted and how quickly it is processed.
A quick check before sending saves time. Pull out anything that is clearly not currency, and expect some heavily damaged items to be excluded after verification. The practical goal is not to make the parcel perfect. It is to give valid coins and notes the best chance of being converted.
Frequently Asked Questions About Coins and Change
Can you exchange foreign coins in the UK
Yes, but usually not through the places people try first. Banks and travel bureaus often refuse coins, especially mixed or low-value foreign denominations. Specialist services are the practical option because they're set up to handle coins as well as notes.
Can you exchange foreign coins and notes together
Yes. That's often the easiest way to deal with leftover foreign currency, especially if you have several countries mixed together. A single submission is usually more convenient than trying to separate every item and solve each one differently.
Do banks accept old or withdrawn foreign currency
Usually not. Banks tend to focus on mainstream, current banking activity, and withdrawn foreign currency falls outside that. Specialist services are more likely to accept obsolete or discontinued issues, including pre-euro currency and older coinage.
Can old coins and change still have value
Sometimes, yes. The key point is that "no longer spendable" doesn't automatically mean "worthless." The Royal Mint estimates that some £7 billion of coins are held outside the formal banking system in the UK, mostly in households, small businesses and charity tins, including older decimal, pre-decimal and foreign coinage according to this overview referencing Royal Mint data. That dormant stock exists precisely because people aren't sure what can still be converted.
Do I need to sort my foreign coins before sending them
Not always. Many people assume they must separate everything by country and denomination before sending it off. Specialist services often make that unnecessary, which is one of the main reasons they're easier to use than banks or exchange counters.
What happens if some items in my parcel aren't accepted
That depends on the service, but proper verification should identify items that fall outside accepted parameters. This is common with damaged coins, tokens, and odd non-currency pieces that get mixed in accidentally. A reputable process will be clear about what's accepted and how any rejected items are handled.
Can charities and businesses use the same kind of service as travellers
Yes. In fact, they often benefit even more because their collections are larger, more mixed, and harder to process manually. A traveller may have one jar. A charity may have several donation points. A business may have regular foreign cash coming in through trade. The core need is the same. Convert awkward currency into usable value.
How long does payment usually take
Timings depend on the provider, but specialist services commonly state their payment process clearly before you send anything. The best systems are upfront about verification, payment method, and what happens if you decide not to proceed.
Can I donate the value instead of receiving cash
Yes, many specialist services offer that option. It's a practical choice for people who don't need the money themselves or for organisations running fundraising drives around leftover holiday currency.
What's the best option for mixed coins and notes from several trips
Use one specialist process and send the full collection together. That's usually more efficient than trying to exchange only the easy notes and leaving the awkward coins behind. The less you split the problem, the more likely you are to solve it fully.
If you've got coins and change sitting at home, in a charity office, or in a business cash drawer, We Buy All Currency offers a straightforward way to convert foreign coins, notes, and withdrawn currency into cash or charity funds. It's built for the situations banks and exchange bureaus usually can't help with, including mixed collections, obsolete money, and unsorted foreign change.
