What are UK pennies made of? Explore Their Composition
Posted by: Ian Stainton • 25 Mar 2026
Ever found a handful of pennies in an old coat pocket and wondered what they’re actually made of? It’s a question with a surprisingly interesting answer. Pennies minted since late 1992 aren't solid bronze or copper at all—they’re actually copper-plated steel.
This change was a clever move by the Royal Mint to keep production costs down, and it created two very different types of modern 1p coins.
The Modern UK Penny: A Tale of Two Metals
The story of the modern penny starts back on 15 February 1971, when Britain went decimal. The original "new pence" coins were made from a bronze alloy: 97% copper, 2.5% zinc, and 0.5% tin. For over two decades, this was the standard.
But then, the price of copper started to climb. It reached a point where the metal in the coin was becoming worth more than the penny itself! To solve this, the Royal Mint switched to a new composition in September 1992: a steel core with a thin copper plating. This simple change slashed the cost of making each coin and gave us an easy way to tell the old from the new.
This timeline clearly shows the shift.
For over 20 years, we had solid bronze pennies, but for the last three decades, they’ve been mostly steel. It’s a fascinating little piece of economic history you can literally hold in your hand.
How to Tell Your Pennies Apart
So, how can you tell which type of penny you have? It’s incredibly simple. All you need is a magnet.
- If the magnet sticks: You have a copper-plated steel penny, minted after mid-1992.
- If the magnet doesn't stick: You have an older, non-magnetic bronze penny from 1971-1992.
Because the older bronze coins are non-magnetic, they fall into the category of non-ferrous metals. The newer coins, with their steel core, are magnetic (ferrous).
This quick comparison table breaks down the key differences between the two types of 1p coins.
UK 1p Coin At a Glance: Bronze vs Steel
| Feature | Bronze Penny (1971 – Mid-1992) | Copper-Plated Steel Penny (Sept 1992 – Present) |
|---|---|---|
| Composition | 97% copper, 2.5% zinc, 0.5% tin | Steel core with copper plating |
| Weight | 3.56g | 3.56g |
| Diameter | 20.3mm | 20.3mm |
| Magnetic? | No (non-magnetic) | Yes (magnetic) |
As you can see, while the coins look and feel almost identical, their core material is completely different. This distinction is what makes the magnet test so effective.

Exploring the Pre-Decimal Penny's Rich History
Long before decimalisation swept through Britain in 1971, the penny was a different beast altogether. These were the 'old pennies'—large, heavy coins that were a familiar part of daily life for generations. Their story isn't static; it's one of constant change, shaped by the same economic forces and security concerns that influence our money today.
Believe it or not, the journey of what pennies are made of is a very old tradition. Originally, these coins were hefty chunks of pure copper. But as the 19th century rolled on, the rising price of copper and a growing headache with counterfeiters pushed the Royal Mint to come up with a new plan.
The Great Bronze Recoinage of 1860
A major turning point came on 1 January 1860. The old copper penny was retired and replaced with a tougher, more cost-effective bronze alloy. The new recipe was 95% copper, 4% tin, and 1% zinc. This blend didn't just save money on production; it also made the coins much harder to fake, a clever move to protect the currency's integrity. You can dig deeper into this milestone on the penny's pre-decimal history page on Wikipedia).
This exact bronze mix became the go-to formula for over 60 years, seeing the country through the reigns of several monarchs:
- Queen Victoria: From 1860 onwards
- King Edward VII: Throughout his entire reign (1902-1910)
- King George V: Right up until 1922
But the story of what these pennies are made of didn't stop there. Major world events would soon force even more changes to their metallic makeup.
The switch to bronze in 1860 wasn't just a material change; it was a strategic defence. By making the coins harder and more complex, the government made them more difficult for counterfeiters to replicate, securing public trust in the currency.
The economic strains of the First World War and its aftermath led to further tweaks. Later, during the Second World War, a shortage of tin meant the coin's composition had to be adjusted once again.

Why the Modern Penny's Composition Changed
The story of what UK pennies are made of has a fascinating twist that happened in the late 20th century. After the big switch to decimalisation in 1971, the new 1p coin was a trusty bronze alloy. But as the 1980s rolled into the 1990s, the Royal Mint found itself facing a serious headache caused by global economics.
The price of copper on the world's commodity markets began to skyrocket. This wasn't just a small blip; it was a huge, sustained price hike. It got to the point where the value of the raw metal in a single 1p coin was worth more than one penny. This created a massive problem: people could literally melt down the coins and sell the metal for a profit, which threatened to throw the entire currency system into chaos.
A Smart Solution to a Growing Crisis
The Royal Mint had to step in and act fast. Letting the situation get any worse simply wasn't an option. Their solution was clever, pragmatic, and ensured the humble penny could stick around as a practical part of everyday life in the UK.
In September 1992, they made the big change. The mint switched from the classic solid bronze alloy to a much cheaper alternative: a mild steel core electroplated with a thin copper coating. This move immediately solved the problem. The new copper-plated steel pennies looked and felt almost identical to the old bronze ones, but they cost far less to produce.
This wasn't just a cost-saving exercise; it was an essential move to protect the coin itself. By making the metal value much lower than its face value, the Royal Mint got rid of any reason for people to melt the coins down, saving the currency from disappearing.
This decision secured the penny's future, allowing it to remain in circulation for decades to come. While these old bronze pennies are no longer spendable in shops, they do still hold value. If you have a jar full of them, along with other leftover foreign currency or old holiday money, there's no need to spend time sorting through them.

How to Identify the Pennies in Your Change Jar
That jar of coins sitting on your shelf is more than just loose change; it’s a miniature museum of modern British history. With just a couple of simple tricks, you can quickly become a coin detective and figure out exactly what you’ve got. We'll walk you through how to easily identify the three main types of pennies you’re likely to find.
Sorting your pennies is much easier than you might think. You don’t need any special equipment at all—just your eyes and a common household magnet will do the trick.
A Quick Sorting Checklist
Here’s a simple checklist to quickly categorise your collection.
Check the size first: Is the coin large and heavy, about the size of a modern £2 coin? If so, you've got a pre-decimal bronze penny, minted before 1971. Their impressive size makes them easy to spot.
Look at the date: For the smaller, modern-sized pennies, the date is your next clue. Coins dated between 1971 and mid-1992 are made from the original bronze alloy.
Use the magnet test: This is the real giveaway. If a penny is dated 1992 or later, hold a magnet to it. If it sticks, you have a modern copper-plated steel penny.
The magnet test is the simplest way to tell the decimal pennies apart. The steel core in coins minted from late 1992 onwards makes them magnetic, while the older bronze coins won't react at all. It’s a dead-simple physical property that instantly reveals the coin's composition.
Once you know what’s what, you might be curious about their weight and how that all adds up. We've got more helpful details on our page explaining UK coin weights and values.
