Breakfast (10p) is served! Your Scarcity Index Update…

It’s time for your latest Scarcity Index update, where we reveal the UK’s most sought-after circulation coins of the last three months! As we’ve been able to go out and spend more cash in recent months, how has this impacted our Scarcity Index?

Well there’s been lots of movement across all of our indexes, as new trends have been exposed and one particular coin has moved an impressive 16 spaces!

You can use the updated A-Z 10p, 50p and £2 indexes below to discover how sought-after the coins in your collection really are.

This information has been compiled using data from the Change Checker Swap Centre and presented in the easy to use indexes below, with arrows to signify how many places up or down a coin has moved since the last Scarcity Index.

A-Z 10p Scarcity Index

It’s English Breakfast time this quarter as this 10p has climbed a huge 16 places on our A-Z 10p Index! This is definitely the one to watch

Whilst the top 8 spots have stayed the same, there have been some really big movers towards the middle and lower half of the table. The Ice Cream and X Marks The Spot 10ps have both dropped 10 and 13 places respectfully, with other big movers including the Union Jack 10p (dropping nine places) and the Fish and Chips 10p (climbing eight places).

All of the lower mintage A-Z 10ps have remained strong at the top of the index; the Y, Z, and W 10ps all have a 2019 mintage of JUST 63,000 so it would take some doing to beat them to the top…

Regardless of where they feature in the above index, if you have any of the A-Z 10ps in your collection you should consider yourself very lucky. A maximum of only 304,000 of each design entered circulation!

50p Scarcity Index

We’ve had a shake up at the top of our 50p Index this quarter, with the Judo 50p being bumped down two spaces from second to fourth spot.

Last quarter our top six 50ps hadn’t moved but this quarter we’ve seen Football climb back to second spot for the first time in three quarters!

There’s also been a lot of shuffling in the middle and lower parts of the index, with Roger Bannister climbing an impressive 10 spots and Handball dropping seven.

The ones to watch are definitely Pentathlon (having climbed 10 places last quarter and a further six this quarter) and Shooting, which climbed two places last quarter and a further two places this quarter. We’re excited to see how these coins place in our next update…

£2 Scarcity Index

Whilst the Commonwealth Games £2 coins have remained consistent at the top of our Index, we’ve now got our Olympic trio sitting beneath, with the Olympic Centenary climbing 3 places and the London 2012 Handover and Olympic Handover £2 coins coming in behind.

After climbing 8 places last quarter, the Florence Nightingale has dropped back down again to the bottom of the Index.

The First World War (Kitchener) £2 has climbed up a space after also climbing two spaces last quarter, so this could be one to watch over the coming months…

How your Scarcity Index works

Generally collectors have had to rely upon mintage figures to identify the scarcest coins.  But they only tell part of the story.  Trying to find a good quality coin from 15 – 20 years ago, even for a higher mintage issue, is much more challenging than a more recent issue, as coins become damaged over time and are ultimately removed from circulation.

Additionally, some designs are more hoarded than others by people who might not normally collect coins – the poignant First World War £2 Coin series being an example. Finally, it can be up to a couple of years before the Royal Mint eventually confirms the actual mintage for an issue.

That’s why we have combined the mintage information with two other key pieces of information.

  • How many of each design are listed as “collected” by Change Checkers, indicating the relative ease of finding a particular coin.
  • The number of times a design has been requested as a swap over the previous 3 months, showing the current level of collector demand.

Importantly, as new coins are released and popularity rises and falls across different designs the Scarcity Index will be updated quarterly allowing Change Checkers to track the relative performance of the UK’s circulation coins.

How much are my coins worth?

The Scarcity Index does not necessarily equate to value but it is certainly an effective indicator.  For example, the Kew Gardens 50p coin commands a premium of up to 200 times face value on eBay.

You can use the 6 point guide to help you determine a more realistic value for your coins.

What about £1 Coins?

The £1 Scarcity Index has already been published for the Round £1 coins and, because they are no longer being issued, this is now set in stone.

The Father of Television – John Logie Baird celebrated on UK 50p

It’s hard to imagine life without television but back in the early 1920s, it was a complete unknown.

That was until John Logie Baird successfully produced televised objects in outline in 1924, transmitted recognisable human faces in 1925, and demonstrated the televising of moving objects in 1926.

To celebrate the life and works of the ‘Father of Television’, a brand new 50p in the UK’s Innovation in Science series has been released, designed by Osborne Ross. a London based design agency.

The design features key milestones from Baird’s life, presented between the lines of transmission radiating from the centre of the coin.

The Father of Television

At the age of 34, John Logie Baird set about experimenting in television – the start of a passion which was to drive him for the rest of his life.

By early 1925, Baird was successful in demonstrating one of his experiments to the public, in Selfridges’ display window on Oxford Street, London. Bemused shoppers were treated to ‘a recognisable, if rather blurred’, image of simple forms such as letters printed in white on a black card.

Baird’s breakthrough came in 1925 when he produced a recognisable image, complete with shades of grey and in 1926 he gave the world’s first public demonstration of television.

To mark this incredible breakthrough in technology, John Logie Baird now joins the likes of Rosalind Franklin and Stephen Hawking in The Royal Mint’s Innovation in Science series as he’s commemorated on a brand new UK 50p.

Innovators in Science Series

In 2019, The Royal Mint confirmed a new series of coins commemorating some of the most influential Innovators in Science.

2019 Stephen Hawking 50p

The series kick-started with a 50p commemorating Stephen Hawking, less than a year after his death.

2019 Stephen Hawking 50p

Hawking’s ‘A Brief History of Time’ enlightened millions to the workings of the universe and revolutionised the way we understand time and space. As an ambassador for science, his significant contributions to humanity have left a lasting presence on all of us.

The striking design by Edwina Ellis features a stylised black hole to reflect his breakthrough work, as well as an inscription of his name and most notable ‘Bekenstein-Hawking formula’ describing the thermodynamic entropy of a black hole.

2020 Rosalind Franklin 50p

In the year that would have marked her 100th birthday, The Royal Mint released a 50p celebrating the life and crucial work of Rosalind Franklin, the first female scientist to be commemorated on a UK coin.

2020 Rosalind Franklin 50p

David Knapton’s striking design of this coin, features a depiction of Rosalind Franklin’s X-ray, ‘Photograph 51’, which revealed the helical structure of DNA, in her laboratory at King’s College, London.

One of Britain’s greatest scientists, Franklin made a crucial finding to the discovery of the double-helix structure of DNA.

Outside of the Innovators in Science series, we’ve seen an impressive selection of engineers and innovations celebrated on our UK coins…

2001 Wireless Transmission £2

In 1901, Guglielmo Marconi, an Italian physicist, succeeded in sending the first radio transmission across the Atlantic Ocean, disproving theories that the curvature of the earth would limit the transmission to 200 miles or less.

The message – simply containing the Morse code signal for the letter ‘s’ – travelled more than 2,000 miles from Poldhu in Cornwall to Newfoundland in Canada and won him worldwide fame and a Nobel Prize in physics in 1909.

2001 Wireless Transmission £2

This £2 coin was issued in 2001 to commemorate the 100th anniversary of this outstanding breakthrough.

4,558,000 of these coins entered circulation.

2004 Steam Locomotive £2

The first steam engine locomotive was built by mining engineer Richard Trevithick and travelled from Merthyr Tydfil in South Wales to Abercynon on its first journey in 1804, carrying 10 tons of iron, 5 wagons and 70 people on the 9 mile trip.

2004 Steam Locomotive £2

This £2 coin was issued in 2004 to commemorate the 200th anniversary of this impressive development in transportation.

The reverse design pays tribute to this first engine known as the ‘Pennydarren‘ which started the growth of railway transport in the 19th Century.

5,004,500 of these coins entered circulation. Have you found one?

2006 Brunel £2

Isambard Kingdom Brunel was an English mechanical and civil engineer whose designs revolutionised public transport and modern engineering.

He is perhaps best remembered for the network of tunnels, bridges and viaducts constructed for the Great Western Railway as well as the Clifton Suspension Bridge which crossed the River Avon.

2006 Brunel – Portrait £2

This £2 coin commemorates the 200th anniversary of his birth in 1806 and features a portrait of Brunel against a section of the Royal Albert bridge, wearing a top hat with a trademark cigar in his mouth.

7,928,250 of these coins entered circulation. Have you found this coin in your change?

2006 Brunel – Paddington Station £2

Brunel is perhaps best remembered for the network of tunnels, bridges and viaducts constructed for the Great Western Railway as well as the Clifton Suspension Bridge which crossed the River Avon.

This £2 commemorates the 200th anniversary of his birth in 1806 and features a section of the roof of Paddington Station – one of his most famous works.

7,452,250 of these coins entered circulation in 2006, making it the rarer of the two Brunel £2 coins.

Is your H.G. Wells £2 coin worth thousands? How to spot if you’ve got an ‘error’ coin!

Every keen collector knows that it is worthwhile paying close attention to the small details of your coins – it’s the only way you can ever hope to spot an error. 

From edge inscription mix ups to inverted effigies, there are a few stories that crop up more often than not. However, recently, a couple of ‘error’ stories have cropped up, that Change Checker really think you should pay attention to – involving an H.G. Wells £2 and the Technology £2…

Stay tuned as we take a closer look at these ‘errors’ and help you determine if your £2 coin is a genuine rarity!

H.G. Wells £2 – Blank ‘Error’

This £2 coin was issued as part of the 2021 UK Commemorative Coin set and it marks the 75th anniversary of the death of science fiction novelist, H. G. Wells.

With the clue in the name, this bi-metallic coin is made up of a combination of a silver coloured cupro-nickel disc and an outer yellow nickel-brass ring.

In the case of this H.G. Wells £2 coin however, it appears that the blank used has a thicker yellow ring, much wider than what we’d see on normal £2 coins.

H.G. Wells £2 Blank ‘Error’ comparison. Source: The SUN.

When striking £2 coins, the first step is to punch a hole through a blank planchet to create the outer section. The inner core is taken from a different metal, sized to fit inside the outer ring.

There have already been estimations that if this coin was to be sold at auction, it could fetch over £1,000! We’re going to be eagerly awaiting confirmation from The Royal Mint whether this error is genuine or not. Nonetheless, it certainly makes for interesting collecting!

This coin is yet to be individually issued, so any ‘error’ versions will have come exclusively from the 2021 UK Annual Set. It’ll certainly be interesting to see if any other stories crop up after the coin’s individual issue….

Whilst there are no identical examples to compare the H.G. Wells £2 ‘error’ to, there have been previous instances of the inner and outer sections of £2 coins not quite matching up:

Clipped Planchet

In the above image, the inner core was punched out from the end of the sheet of metal used for blanks, forming a straight or ragged edge clip.

Whilst this also occurs with monometallic coins, the pairing with an outer ring exposes a large gap which is much more noticeable.

The Royal Mint strike millions of coins each year so it is inevitable that variances will occur during the striking process and can’t always be picked up during quality control, despite the fact that this particular coin would weigh less than the standard 12g £2 coin.

Off Centre Inner Core

The inner core of this coin hasn’t been united properly prior to being struck, resulting in an off centre inner core.

Due to the way the inner and outer core are struck together with the two metals being lined up and then fused together during striking, a misalignment will mean that the inner core spills into the outer ring, as seen in the image above. There might also be a gap between the two metals on the opposing join.

Faulty Outer Ring

This particular mis-strike, shows a faulty planchet or outer ring, where the inner core is exposed.

In the image above, you can actually see the specific engineering design features where the inner core is grooved to help the metal flow bond to the outer ring and fuse during striking.

Similar to the first mis-strike we looked at, this could be caused by a clipped planchet, this time created when the outer ring was punched, however coins like this may also be caused by tampering post striking, for example by fakers trying to replace the inner core of a £2 with another coin to pass off as a rare error.

Bronze £2 Error

2010 ‘Bronze’ Technology £2. Send to Change Checker by Amin.

The ‘Monometallic’ £2 is described as the Holy Grail of bimetallic ‘errors’ and is the result of the nickel-brass £2 blank not having the inner core section punched out before being struck.

This means that the £2 coin is made from one full piece of nickel-brass, completely contrasting the very idea of a bimetallic coin.

A 2007 monometallic £2 was verified by The Royal Mint and in the email confirming the mis-strike it was mentioned that they had only seen 4-5 similar coins before.

However, in 2021, Change Checker was contacted by a collector called Amin who informed us that he had found this exact error coin but with a 2010 date.

After sending details of his coin to The Royal Mint for further information, it was confirmed to be genuine error as a result of the minting process.

Letter sent to the collector from The Royal Mint confirming it’s genuinity.

This rare striking error is highly sought-after and coins have achieved extraordinary prices in private sales and auctions.

Whilst information of this coin’s sale has remained private, it’s certainly a very interesting story and we imagine the collector can expect to see a very impressive return on this coin…


We look forward to the individual release of the HG Wells £2 later this year and will certainly be keeping our eyes peeled for any unusual looking variations!
