You're standing at a checkout in London. You reach into your wallet, pull out a crisp, paper-like rectangle, and hand it over. The cashier freezes. They look at the bill, then at you, then back at the bill. If you're holding a 100 pound currency note, this isn't just a normal transaction. It's an event. Mostly because, for the vast majority of people living in England and Wales, a note of that denomination simply doesn't exist in their daily lives.
It’s weird, right? We have fifties. We have twenties. But the 100 pound note is this elusive creature that exists in some parts of the UK but is basically a myth in others.
The Bank of England—the guys who actually run the show for the British Pound Sterling ($GBP$)—doesn't issue them. If you walk into a high-street bank in Manchester or Birmingham and ask for a hundred-pound note, they’ll look at you like you’ve grown a second head. However, if you hop on a flight to Edinburgh or Belfast, things get a lot more interesting.
Who actually prints a 100 pound currency note?
Scotland and Northern Ireland are the wild west of British currency. Well, maybe not "wild west," but they certainly have more freedom. Under the Banking Act 2009, three Scottish banks (Bank of Scotland, Royal Bank of Scotland, and Clydesdale Bank) and several Northern Irish banks have the legal right to issue their own banknotes.
These aren't "Monopoly money." They are legal currency. They are backed by assets held at the Bank of England to ensure they have value. And yes, these banks actually print a 100 pound currency note.
Take the Bank of Scotland, for example. Their £100 note features Sir Walter Scott on the front. On the back, you’ll find an image of the Glenfinnan Viaduct—the famous bridge from the Harry Potter movies. It’s a beautiful piece of design. But try spending that in a corner shop in Cornwall, and you’re going to have a bad time.
The problem isn't that the money isn't real. It's that English retailers aren't legally required to accept it. In fact, "legal tender" is a phrase that people throw around a lot without actually knowing what it means. In England, only Bank of England notes are technical legal tender. Scottish notes are "legal currency," which basically means they are a valid way to pay, but a shopkeeper can say "no thanks" just because they've never seen one before and don't want to risk it being a fake.
The Giant and the Titan: The secret 100 million pound notes
Okay, let's get into the really cool, slightly terrifying stuff. There are notes that make a 100 pound currency note look like pocket change. We're talking about the "Giants" and the "Titans."
These aren't for you. You will never hold one. If you are holding one, you’ve probably committed a very high-level heist.
To back the value of the notes printed by Scottish and Northern Irish banks, the Bank of England requires those banks to hold an equivalent value in Bank of England notes or assets. Instead of filling a room with millions of £5 notes, the Bank of England printed special high-value notes to be held in their vaults.
- The Giant: A note worth £1,000,000.
- The Titan: A note worth £100,000,000.
These exist purely for internal accounting. They are about the size of an A4 piece of paper. Imagine losing one of those in the wash. They serve as the physical bedrock that allows a Scottish 100 pound currency note to have actual purchasing power. Without the Titans sitting in a vault in London, the paper printed in Edinburgh wouldn't be worth the ink on it.
Why doesn't England have a 100 pound note?
It feels like a gap, doesn't it? The US has the $100 bill (the "Benjamin"). The Eurozone has the €100 and even the €200 (they phased out the €500 because it was the favorite of money launderers). So why does the Bank of England stop at £50?
The answer is honestly pretty boring: crime and convenience.

Higher denomination notes are a dream come true for people trying to move large amounts of cash illegally. You can fit way more "value" into a suitcase if you're using hundreds instead of twenties. The Bank of England has historically been wary of making life easier for tax evaders and organized crime.
Plus, we just don't use cash like we used to. With the rise of contactless payments and Apple Pay, even the £50 note is becoming a rarity. Most ATMs in the UK only dispense £10s and £20s. If the bank started circulating a 100 pound currency note in London, most shops wouldn't have enough change in the till to break it if you bought a £3 coffee.
The Polymer Revolution
You've probably noticed that British money feels like plastic now. That’s because it is. Polymer notes were introduced to be more durable and much harder to counterfeit.
The Scottish banks followed suit. When they updated their designs, the 100 pound currency note got the polymer treatment too. For instance, the Royal Bank of Scotland (RBS) released a polymer £100 note featuring Flora Stevenson, a social reformer and pioneer of women's education.
These new notes are high-tech. They have holographic windows, color-shifting ink, and "tactile" features to help visually impaired people identify the denomination. They are basically tiny pieces of plastic art. But again, their rarity is their defining feature. Because they aren't circulated heavily, many people—even in Scotland—might go months without seeing one.
What should you do if you find yourself with one?
Let's say you've been working in Glasgow, you get paid in cash, and you've got a few of these hundreds in your pocket. Then you hop the border back to London.
First off, don't panic. You haven't lost your money. But you should be strategic.
Don't go to a small "Mom and Pop" grocery store. They will almost certainly refuse it because they don't want the risk. Your best bet for spending a Scottish or Northern Irish 100 pound currency note in England is a major department store (like Selfridges or Harrods) or a large supermarket chain. Their staff is usually better trained to recognize different types of UK currency.
Better yet? Go to a bank.
Any major UK bank will take a Scottish £100 note and swap it for Bank of England twenties without a fuss. They might ask for ID if you aren't a customer, but it’s the cleanest way to "liquidate" your high-value Scottish notes into something more spendable south of the border.
The Collector's Market
There is a whole world of people who obsess over these notes. "Numismatists" (coin and note collectors) hunt for specific serial numbers. If you happen to have a 100 pound currency note with a "low" serial number—like AA01 000001—it is worth way more than £100.
In 2021, a rare Bank of Scotland £100 note from the Victorian era sold at auction for thousands of pounds. Even modern ones can fetch a premium if they are in "uncirculated" (perfect, crisp) condition.
So, if you ever get one, take a look at it. If it looks special, maybe don't spend it on groceries just yet.
Making sense of the confusion
It’s easy to get frustrated by the UK's weirdly fragmented currency system. Why can't we just have one set of notes?
It comes down to tradition and identity. Scotland and Northern Ireland take great pride in their banking heritage. These notes are a symbol of their distinct economic history. While it might be a bit of a headache for a tourist trying to figure out if their money is "good," it adds a layer of complexity and character to the UK's financial landscape.

The 100 pound currency note remains a bit of an outlier—a high-value ghost that haunts the tills of the UK. It’s a reminder that money is as much about trust and local custom as it is about official government decree.
Actionable steps for handling high-value UK notes
If you’re dealing with or searching for a hundred-pound note, here is the ground truth on how to handle it:
- Check the Issuer: Look at the top of the note. It will say Bank of Scotland, Royal Bank of Scotland, Clydesdale Bank, or one of the Northern Irish issuers like Bank of Ireland or Ulster Bank. If it says "Bank of England," you’ve got a counterfeit or a historical relic, because they don't make them for the public.
- Verify the Security Features: Feel the raised print on the "100" and the bank's name. Look for the clear window and the holographic image that changes when you tilt the note. If it’s a modern polymer note, it should feel like flexible plastic, not paper.
- Deposit, Don't Spend: If you are in England, save yourself the embarrassment of a rejected payment. Take the note directly to a post office or a bank branch. They are the most reliable places to exchange it or deposit it into your account.
- Travelers Beware: If you are a tourist leaving the UK, try to spend or exchange your Scottish/Northern Irish notes before you leave. Foreign exchange bureaus outside the UK often give much worse rates for "regional" UK notes compared to Bank of England notes—if they accept them at all.
- Look for the "First Prefix": If you’re interested in the collector's value, check the serial number prefix. Notes starting with "AA" or "AA01" are generally more desirable to collectors and should be kept in a protective sleeve.
The 100 pound currency note might be rare, but it is a perfectly legitimate part of the British economy. Just don't expect to use it to buy a pint of milk in London without a few raised eyebrows.
