The 1 pound coin is a staple of British currency, with a rich history and a variety of designs. This FAQ covers everything from its dimensions and value to its rarity and how to collect it.
What is the 1 pound coin?
The 1 pound coin is a circulating coin of the United Kingdom, currently made of a bimetallic design (nickel-brass outer ring and nickel-plated inner core). It was first introduced in 1983, replacing the £1 banknote. The coin is legal tender for any amount, but its practical use is for everyday transactions. The current design features a 12-sided shape, introduced in 2017 to deter counterfeiting.
Key features of the 2017 coin include a hologram-like image that changes from a '£' symbol to the number '1' when tilted, and micro-lettering around the edge. The coin weighs 8.75 grams and has a diameter of 23.43 mm.
How much is a 1 pound coin worth?
All 1 pound coins are worth exactly £1 in face value, but some are worth far more to collectors. Certain rare designs or error coins can sell for hundreds or even thousands of pounds. For example, the 2011 'Edinburgh City' coin had a low mintage (935,000) and is worth around £3-£5 in circulated condition, but uncirculated examples can fetch more. The 2009 'Royal Arms' coin is also relatively scarce.
To check if your coin is valuable, look for:
- Low mintage years (e.g., 2011, 2015)
- Minting errors (e.g., double strike, wrong planchet)
- Uncirculated condition (graded MS65 or higher)
- Rare designs from specific mints (e.g., Edinburgh, Cardiff)
How much does a 1 pound coin weigh?
The current 1 pound coin weighs 8.75 grams. This is the weight for the 2017-present bimetallic coin. The older, round 1 pound coins (1983-2016) weighed slightly less at 9.5 grams for the nickel-brass versions. The weight is important for vending machines and for counterfeit detection.
For comparison, a 2 pound coin weighs 12 grams, and a 50 pence coin weighs 8 grams. If you have a coin that feels unusually light or heavy, it may be a fake.
When did the 1 pound coin change to the 12-sided design?
The 1 pound coin changed to the current 12-sided design on 28 March 2017. This was the biggest change to UK coinage in decades, introduced to combat counterfeiting, as an estimated 1 in 30 old round £1 coins were fake. The new design was created by coin designer David Pearce and features the Royal Shield on the reverse. The old round coins were demonetised on 15 October 2017, meaning they are no longer legal tender.
However, you can still exchange old round £1 coins at the Bank of England or some post offices, but only for a limited time.
What are the rarest 1 pound coins?
The rarest 1 pound coins are those with low mintages, especially from the 2011 'City' series. The rarest is the 2011 Edinburgh City coin, with only 935,000 minted, followed by the 2011 Cardiff City coin (1.6 million). Other rare editions include the 2009 Royal Arms (2.5 million) and the 2015 (unlike the 2016, the 2015 has a lower mintage of around 2.4 million).
In terms of value, a 2011 Edinburgh in uncirculated condition can sell for over £20, while circulated examples go for £3-£5. Error coins, such as the 2017 coin with a 'double die' error, can be worth hundreds. Always check the mint mark and condition.
How to check if a 1 pound coin is valuable?
To check if a 1 pound coin is valuable, follow these steps:
- Identify the year and design: Look for the date on the obverse (heads) side.
- Check the mintage: Low mintage years (e.g., 2011, 2015) are generally more valuable.
- Look for errors: Misprints, double strikes, or missing edge lettering can increase value.
- Assess condition: Uncirculated coins (no wear) are worth more.
- Consult a price guide: Use reputable sources like the Royal Mint's website or coin collecting forums.
Remember, many coins are only worth face value, so don't get your hopes up unless you have a rare edition.
Can you still use old 1 pound coins?
No, old round 1 pound coins are no longer legal tender. They were demonetised on 15 October 2017, meaning they cannot be used in shops or banks as currency. However, you can still exchange them for new coins at the Bank of England (in person or by post) or at some UK post offices. Some banks may also accept them for deposit into your account, but this is not guaranteed.
If you have old coins, it's best to exchange them sooner rather than later, as the Bank of England may eventually stop accepting them.
What are the designs on the 1 pound coin?
The 1 pound coin has had many designs over the years, reflecting British heritage, landmarks, and symbols. The current 12-sided coin features the Royal Shield on the reverse, which is divided into four quadrants representing England, Scotland, Wales, and Northern Ireland. The obverse features the portrait of Queen Elizabeth II (or King Charles III on newer 2023 issues).
Older round coins had a variety of designs:
- 1983-1984: Royal Arms
- 1985-1993: Various regional symbols (e.g., thistle, leek, rose)
- 1994-1998: Floral emblems
- 1999-2008: Various symbols like the lion, dragon, and bridge
- 2008-2016: Royal Shield (same as current)
1 pound coin vs 2 pound coin: what's the difference?
The main difference between the 1 pound and 2 pound coins is their value and physical characteristics. The 2 pound coin is larger (28.4mm diameter) and heavier (12g) than the 1 pound coin (23.43mm, 8.75g). The 2 pound coin also features a bimetallic design with a nickel-brass outer ring and a copper-nickel inner disc, similar to the 1 pound but with a different colour distribution.
Both coins have been used for commemorative issues, but the 2 pound coin is often used for special events, while the 1 pound coin has a more everyday circulation. In terms of value, some 2 pound coins, such as the 2002 Commonwealth Games Northern Ireland issue, can be worth more than face value, but generally, the 1 pound coin has more rare circulation issues.
Final Thoughts
The 1 pound coin is more than just a piece of change; it's a piece of British history. From its humble beginnings in 1983 to the modern 12-sided marvel, it has adapted to combat counterfeiting and celebrate the nation's heritage.
Whether you're a collector looking for a rare find or just curious about the coin in your pocket, understanding its specifications, designs, and values can be both fun and profitable. Always check for rare dates and errors, and consider grading your coins for a better price.
As we move into 2026, the 1 pound coin continues to be a vital part of UK currency, with new designs featuring King Charles III. Keep an eye out for future issues—you never know which one might become the next valuable rarity.
