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.

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!

To celebrate the 90th Birthday of Her Majesty Queen Elizabeth II The Royal Mint issued a new commemorative £5 coin.

This coin features a design by Christopher Hobbs, depicting nine roses, inspired by Her Majesty’s love of flowers – one for each decade of Her Majesty’s life.

You’ll notice the flowers in the wreath are each different to the next one. As this was such a personal occasion, Hobbs chose to move away from heraldic flowers and to use a more natural floral image instead.

The obverse features the fifth portrait of Her Majesty the Queen, designed by Royal Mint engraver Jody Clark.

In 2012, the Queen celebrated her Diamond Jubilee having reached 50 years on the throne.

This is the first coin ever struck to commemorate a Diamond Jubilee – there were no special coins for Queen Victoria’s in 1897. The obverse features a new portrait of Her Majesty crowned and wearing the robes of the Order of the Garter, created especially for the Diamond Jubilee by Ian Rank-Broadley.

Also designed by Ian Rank-Broadley, the obverse features a portrait of the young Queen Elizabeth just as she appeared in her first portrait with the Latin words DIRIGE DEUS GRESSUS MEOS (May God Guide My Steps).

2002 UK Golden Jubilee £5

In 2002, to mark the 50th anniversary of the Queen’s accession to the throne, the Royal Mint produced this £5 coin.

On one side appears an unusual bust portrait of the Queen wearing the robes of state. The dramatic impact of this motif are heightened by the absence of any inscription other than the value in small lettering around the foot.

The reverse design, as with the original Coronation crown of 1953 features the Queen on horseback. The Latin motto AMOR POPULI PRAESIDIUM REG(inae) meaning ‘The love of the people is the Queen’s protection’ was last used on the coinage of Charles I.

We can’t wait to reveal to you the new 2021 coin designs and I’m sure you’ll agree that there are some really fantastic coins to look forward to.

So let’s kick off the year with the coins we’ve all been waiting for, the 2021 Annual Set…

Decimal Day 50p

2021 Decimal Day 50p available within the 2021 Annual Coin Set

This year marks the 50th anniversary since Decimal Day on the 15th February 1971 and to celebrate the biggest change our UK coinage has ever seen, a brand new 50p has been issued.

In commemoration of the anniversary, this brand new 50p, designed by Dominique Evans, features the original Machin portrait of Queen Elizabeth II on the obverse, which featured on the very first 50p back in 1969.

The 50p has become the most-collected and best-loved decimal coin since its introduction and given the significance of this anniversary, I’m sure this 50p will prove very popular with collectors.

John Logie Baird 50p

2021 John Logie Baird 50p available within the 2021 Annual Coin Set

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

That was until John Logie Baird successfully produced televised objects in outline in 1924, transmitted recognizable human faces in 1925, and demonstrated the televising of moving objects in 1926. This was the very first-time that television had become a reality and it shaped the world that we live in today.

This brand new 50p, designed by Osborne Ross, celebrates the life and works of this remarkable British inventor, electrical engineer, and innovator.

H. G. Wells £2

2021 H. G. Wells £2 available within the 2021 Annual Coin Set

Herbert George Wells was an English novelist, journalist, sociologist, and historian best known for his science fiction novels The Time Machine and The War of the Worlds.

In the year marking the 75th anniversary of his death, this brand new £2 coin has been issued, feature a design which pays a fitting tribute to his famous novels, with a depiction of the Invisible Man and a Martian encircled by clock numerals.

The inscription also reads one of his famous quotes, “GOOD BOOKS ARE THE WAREHOUSES OF IDEAS”. We love Chris Costello’s design and we hope you do too!

Sir Walter Scott £2

2021 Sir Walter Scott £2 available within the 2021 Annual Coin Set

2021 commemorates the 250th anniversary of the birth of novelist, historian, and poet, Sir Walter Scott.

He is considered both the inventor and the greatest practitioner of the historical novel.

The coin, designed by Stephen Raw, features the text: “SIR WALTER SCOTT NOVELIST HISTORIAN POET” encircled by the inscription “250TH ANNIVERSARY OF HIS BIRTH” and the year date.

Excitingly, this coin also features the edge inscription, “THE WILL TO DO, THE SOUL TO DARE”, a quote from his epic poem, ‘Marmion: A Tale of Flodden Field’.

Queens Elizabeth II 95th Birthday £5

2021 Queen Elizabeth II 95th Birthday £5 available within the 2021 Annual Coin Set.

This year, our Queen will celebrate her 95th birthday and to celebrate, The Royal Mint has issued this £5 coin.

The coin features a design by Timothy Noad, of the Royal Cypher and the inscription “MY HEART AND MY DEVOTION” alongside the date of the Queen’s birth and the year 2021.

In 2016, a £5 coin was issued to celebrate Her Majesty’s 90th Birthday and it proved incredibly popular with collectors, as she became the first British monarch to reach their 90th birthday. As she reaches another significant milestone, I’m sure this celebratory coin will prove just as, if not more popular!


The announcement of the new annual coins is always an exciting moment for Change Checkers, particularly when the anniversaries are as significant as these.
