You’ve seen it a thousand times on price tags and news tickers. That curvy, elegant £ looks like a piece of high-end calligraphy, but it’s actually a 2,000-year-old hangover from the Roman Empire. Honestly, most people just call it the "pound sign" and move on, but the story behind the symbol for Great Britain pound is a mess of ancient weight units, medieval scribbles, and a very confusing name-share with the American hashtag.
The symbol isn't just an "L" for the sake of it. It stands for libra, which is Latin for scales or balance. If you’ve ever wondered why the abbreviation for a pound of sugar is "lb," you’re looking at the exact same root. The Romans used libra pondo to mean "a pound by weight." Eventually, the British just kept the libra for the symbol and the pondo for the spoken word. Kinda weird when you think about it—we write one word and say another.
Why the "L" Has a Bar Through It
Ever tried to read a 17th-century letter? Handwriting was a disaster. Back then, scribes would throw horizontal strikes through letters to show they were abbreviations and not just random characters. That single (or sometimes double) bar across the £ was basically a medieval "don't mind me, I'm just a shorthand" notification.
There is no "official" rule about whether it needs one bar or two. The Bank of England has switched it up over the centuries. Their first banknotes in the late 1600s had a very flowery, double-barred version. By the time they got to the modern "D" series of notes in the 1970s—the ones with Isaac Newton and Florence Nightingale—they settled on the single bar we see today. It was purely a design choice.
The double bar is still around, though. You’ll see it in certain fonts or older printing presses. It doesn't change the value; it’s just a stylistic quirk. In the world of Unicode (the tech standard that makes sure your phone and my laptop see the same thing), the symbol for Great Britain pound lives at U+00A3.
Don't Call it a Hashtag
If you’re in the US and you ask for the "pound sign," someone is going to point you toward the # key. In the UK, that’s a "hash." This causes endless headaches for tech support and international phone calls.
The # symbol actually evolved from the same libra pondo roots. Scribes would write "lb" with a line across the top, and as they got faster and sloppier, the "l" and the "b" smashed together until they looked like a grid. While the UK kept the elegant £ for money, the US took the messy scribbled version and made it a "pound" of weight, which eventually migrated onto telephone keypads in the 1960s.

How to Actually Type the £ Symbol
If you aren't using a British keyboard, finding this thing is a nightmare. You're usually staring at a dollar sign and wondering where the "real" money went.
- On a Mac: This is actually the easiest one. Just hit Option + 3. It doesn't matter if your keyboard is American or European; Apple kept it simple.
- On Windows (US Keyboard): You have to do the "Alt code" dance. Hold down the Alt key and type 0163 on your number pad. It won't work with the numbers across the top of the keyboard—has to be the pad on the right.
- On Windows (UK Keyboard): Just hit Shift + 3.
- On Mobile: Long-press the $ sign on your digital keyboard. A little menu will pop up with the Euro, the Yen, and our friend the pound sterling.
Basically, if you’re doing business in London but working from a laptop bought in New York, you’re going to memorize "Alt + 0163" pretty fast.
The "Sterling" Confusion
We call it the "pound," but its formal name is Pound Sterling. Why? Because back in the year 775, "sterlings" were small silver coins used in Saxon kingdoms. 240 of them weighed exactly one pound.

When you see the symbol for Great Britain pound, you’re looking at a literal weight of silver. Even today, the British currency system has these weird echoes of its physical past. For instance, two 1p coins weigh exactly the same as one 2p coin. It’s a carryover from when the value of the money was the metal itself.
Common Mistakes with the Symbol
People mess up the placement all the time. Unlike some European countries where they put the currency symbol after the number (like 10€), the pound sign always goes before the number.
Correct: £50
Incorrect: 50£
Also Incorrect: £ 50 (Don't put a space in there!)
Also, keep in mind that the symbol for Great Britain pound is for the UK currency only. Even though the Egyptian Pound and Lebanese Pound use the word "pound," they have different symbols or use "L.E." or "LL." If you use the £ symbol in a contract for Egyptian pounds, you’re legally asking for a lot more money than you think.
Actionable Next Steps
If you are setting up an international business or just traveling, here is how to handle the symbol properly:
- Check your Spreadsheet: If you're using Excel or Google Sheets, don't just type the symbol. Use the "Format as Currency" tool and select "English (United Kingdom)." This ensures the math works and the symbol is placed correctly.
- Verify the Code: In formal banking, the symbol is often replaced by the code GBP. If you are sending an international wire transfer, use GBP to avoid any ambiguity about which "pound" you mean.
- Keyboard Mapping: If you type this symbol often, go into your computer settings and add "English (United Kingdom)" as a secondary keyboard layout. You can toggle between US and UK layouts with a quick shortcut (usually Win+Space), making Shift+3 your best friend.
