Most Valuable Metal Detecting Finds in the UK
‘m always interested in different ways people manage to make a bit of extra money. Some people flip items on eBay, some complete online surveys, and others rent out spare rooms.
But there’s another side hustle that has always fascinated me: metal detecting.
The UK is one of the best places in the world for it. With thousands of years of history buried beneath fields and farmland, detectorists regularly uncover Roman coins, Viking jewellery and even huge treasure hoards.
Most people will only find the occasional coin or button. But every now and then someone uncovers something worth hundreds of thousands — or even millions — of pounds.
Here are some of the most valuable metal detecting finds in the UK and the British Isles, and what happened after they were discovered.
What is the most valuable metal detecting find in the UK?
The most valuable metal detecting find in the UK is widely considered to be the Staffordshire Hoard, which was officially valued at £3.285 million when it was discovered in 2009.
However, the Grouville Hoard, discovered in Jersey, may actually be worth even more. The Jersey government paid £10 million in 2021 to acquire the treasure and keep it on the island.

The Grouville Hoard – £10 million
The Grouville Hoard is one of the largest collections of Celtic coins ever discovered in the British Isles.
It was found in 2012 on the island of Jersey by detectorists Reg Mead and Richard Miles, who had actually spent more than 30 years searching for the site.
The hoard contains an estimated 70,000 to 80,000 coins, buried inside a clay vessel around 30–50 BC during the late Iron Age.
The coins were minted by the Coriosolitae tribe, who lived in what is now Brittany in northern France. Historians believe the treasure may have been buried for safekeeping during the Roman expansion into Gaul.
In 2021, the Government of Jersey paid £10 million to the finders and landowner to acquire the hoard and keep it on the island.
Many of the coins are now displayed by Jersey Heritage.
The Chew Valley Hoard – £4.3 million
The Chew Valley Hoard was discovered in Somerset by metal detectorists Lisa Grace and Adam Staples.
The hoard contains over 2,500 silver coins from the late Anglo-Saxon and early Norman period.
The coins were buried around the time of the Norman Conquest of 1066, one of the most dramatic turning points in English history.
Among the coins are examples from the reigns of:
• Edward the Confessor
• Harold II
• William the Conqueror
In 2024, the hoard was officially valued at £4.3 million and acquired by the South West Heritage Trust to keep it in Somerset.
The Staffordshire Hoard – £3.285 million
The Staffordshire Hoard is one of the most famous metal detecting discoveries ever made in Britain.
It was discovered in 2009 by detectorist Terry Herbert in a field near Hammerwich in Staffordshire.
The hoard contained more than 3,500 Anglo-Saxon artefacts, including:
• gold sword fittings
• weapon decorations
• jewellery
• fragments of military equipment
Most pieces date from the 7th or 8th century and are decorated with intricate gold filigree, garnets and enamel.
The hoard was officially valued at £3.285 million, with the reward shared between the finder and landowner.
Museums in Birmingham and Stoke-on-Trent raised the funds needed to acquire the hoard and keep it on public display.
The Hoxne Hoard – £1.75 million
The Hoxne Hoard is one of the most important Roman treasure finds ever made in Britain.
It was discovered in 1992 by metal detectorist Eric Lawes in Suffolk after a farmer asked him to help locate a lost hammer.
Instead, he uncovered a buried chest containing:
• over 15,000 Roman coins
• gold jewellery
• silver spoons
• ornate tableware
The hoard dates from the late Roman period (4th–5th century AD).
At the time of discovery it was valued at £1.75 million, though historians estimate the equivalent value today would be closer to £3.8 million.
The treasure is now held by the British Museum.
The Henry III Gold Penny – £648,000
One of the most remarkable individual coins ever discovered by a detectorist is the Henry III gold penny.
The coin was discovered in 2021 near Hemyock in Devon by detectorist Michael Leigh-Mallory.
It dates from 1257 and is one of only eight known examples of the coin in existence.
Because of its extreme rarity, the coin sold at auction for £648,000, making it one of the most valuable medieval coins ever found in the UK.
Interestingly, the finder initially posted photos of the coin online before realising just how rare it was.
The Frome Hoard – £458,000
The Frome Hoard was discovered in 2010 by detectorist Dave Crisp in Somerset.
The hoard contained over 52,000 Roman coins, buried inside a large pottery vessel during the 3rd century AD.
Many of the coins feature the Roman emperor Carausius, who declared himself ruler of Britain during a rebellion against Rome.
The hoard was eventually acquired by the Museum of Somerset after a successful fundraising campaign.
The Ringlemere Cup – £270,000
The Ringlemere Cup is a rare piece of Bronze Age gold discovered in Kent in 2001 by detectorist Cliff Bradshaw.
The cup dates back around 3,500 years, to roughly 1700–1500 BC.
Made from a thin sheet of gold, the cup stands just 8.5 cm tall, yet is decorated with intricate patterns and circular designs.
Experts believe it was likely used for ceremonial or ritual purposes.
The British Museum acquired the cup for £270,000, though its historical importance means its true value today would likely be far higher.
Can you keep what you find metal detecting in the UK?
This is the question most people ask when they hear about these discoveries.
The answer is sometimes.
Metal detecting in England and Wales is governed by the Treasure Act 1996, which was expanded in 2023.
Under the rules, items may be classed as treasure if they are:
• over 300 years old and made of gold or silver
• groups of coins found together
• prehistoric metal artefacts
• objects over 200 years old that are considered historically significant
If a find is classed as treasure, it legally belongs to the Crown.
However, museums can purchase the item at market value, and the reward is usually split between the finder and the landowner.
Who do you report finds to?
Although treasure must legally be reported to the local coroner within 14 days, most detectorists first speak to a Finds Liaison Officer (FLO).
These experts work with the Portable Antiquities Scheme, a nationwide programme that records archaeological finds discovered by members of the public.
They help identify items and decide whether they may qualify as treasure.

What equipment do you need to start metal detecting?
Getting started doesn’t require a huge investment.
Most beginners start with:
Metal detector
Entry-level detectors can cost £80 to £100, while advanced machines can exceed £1,000.
Headphones
These help you hear faint signals more clearly.
Digging tool
A small shovel or trowel is essential.
Finds pouch
A pouch keeps coins and artefacts safe while you continue searching.
Many hobbyists also buy pinpointers, which help locate objects precisely once a hole has been dug.
Can you go metal detecting anywhere?
No.
If you want to metal detect on land you don’t own, you must get permission from the landowner first.
Detecting without permission can be considered illegal activity known as “nighthawking”, which involves searching protected land or archaeological sites without authorisation.
Even beaches and parks may have restrictions, so it’s always best to check with the local council before you start.
And always treat the land with respect. Fill in holes and avoid damaging crops — otherwise you probably won’t be invited back.
Can you make money metal detecting?
Most people won’t get rich metal detecting.
Many detectorists spend years finding nothing more exciting than coins, buttons and bits of scrap metal.
But every now and then someone uncovers a genuine piece of history worth a small fortune.
And with discoveries like the ones above, it’s easy to see why the hobby continues to grow.
New finds are still being made regularly across the UK, from Roman coin hoards to Viking jewellery, proving there’s still plenty of history waiting to be discovered.
Even if you never uncover treasure, there’s still something exciting about digging up an object that hasn’t been touched for hundreds — sometimes thousands — of years.
Not a bad way to spend a Sunday afternoon.
