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.

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!

75th Anniversary of VE Day marked by FIVE world-renowned Mints

2020 marked the 75th anniversary of Victory in Europe Day, and the official end of the Second World War.

Following the Allies’ acceptance of Nazi Germany’s unconditional surrender on the 8th May 1945, the war in Europe had finally come to a close after a long five years of conflict.

Most UK collectors will be familiar with the United Kingdom 75th Anniversary of Victory in Europe Day £2 coin issued earlier this year to commemorate the historic event.

However, Allied Nations across the globe have been commemorating 75 years since the end of the Second World War and this important anniversary has been marked with unique coin issues from some of the world’s most renowned Mints.

Coins issued by the Netherlands, Canada, France, and Belgium, in addition to the UK £2, have been brought together for the first time in the remarkable 75th Anniversary of VE Day Allied Nations Coin Pack.

Only 15,000 Silver-Plated pieces are available worldwide!
