The 20p coin that could make you a mint!

Have you ever noticed something particularly unusual about one of your coins? Perhaps a missing date, denomination or an error in the design?

Well, that’s what happened to one collector who noticed something unique about their 20p coin…

A ‘spectacular error’

The 20p in question was minted in 1990 for a British overseas territory, and was sold as part of a set. However, instead of having the usual cupro-nickel finish, it was struck on a copper-plated blank intended for a different country.

Collector, Alun Barker saw this unusual coin listed on eBay in December 2017 and bought it for just £50. But he was pleasantly surprised when, just a month later in January 2018, the coin was confirmed as a genuine error by The Royal Mint, who issued a certificate of accreditation. They also confirmed it was the only known 20p in existence with with error, making it one of a kind!

Exceeding expectations at auction

Alun decided to have the coin valued by specialists, Tennants Auctioneers, who initially estimated it could fetch as much as £1,200 at auction. However, when he decided to part with the coin in August 2023, Alun was astonished to find out it had sold for a whopping £1,400!

Not the first rare 20p error…

The ‘Bronze 20p’

In 2017, collector David Crosier found a 20p coin with an unusual finish, which he assumed to be bronze plated. He sent the coin to The Royal Mint to check, and after x-ray fluorescence spectrometry, they confirmed it was a genuine minting error.

Somehow, a 1p blank had made its way into the presses and a 20p was mistakenly struck onto it.

The undated 20p

Considered by many as the ‘Holy Grail of change collecting’, the undated 20p is undoubtedly at the top of most serious collectors’ wish lists. In 2008, an unknown number of 20p coins were released into circulation without a date on either the obverse or reverse. This followed a die mix up after the new Royal Shield design was introduced.

The Royal Mint confirmed this was the first time in over 300 years that a coin had entered circulation without a date, making it extremely sought-after by collectors. They also confirmed that, whilst exact quantities are unknown, no more than 250,000 of these undated coins made it into circulation.

These coins have been listed on the secondary market with a value as high as £10m, however you should always check the sold listings on secondary market sites to see how much collectors are actually willing to pay for a coin.

Our latest eBay Tracker shows that the undated 20p is currently selling for around £52.

The 2p drought returns…2022 Mintage Figures REVEALED!

One of the biggest numismatic updates of the year comes when the latest mintage figures are announced, and The Royal Mint have just revealed the mintages of all coins that entered circulation in 2022! Each year, when this information is released, we update our Change Checker Mintage charts to see where new circulating coins rank.

We saw millions of almost every denomination enter circulation in 2022, however there was one denomination that you won’t find with a 2022 date in your change…read on to find out more.

Three commemorative 50p designs entered circulation in 2022, as well as the definitive Royal Shield 50p design. It was a year of ‘firsts’ as the 2022 Platinum Jubilee 50p was the first ever royal 50p to be issued and the Queen Elizabeth Memorial 50p was the first ever UK coin issued bearing King Charles III on the obverse.

With the Queen Elizabeth Memorial 50p marking a new era of coinage featuring the King, many collectors old and new were excited to find it in their change. We opened our collector map to track where they were popping up across the country, and it turned out the place most people found one was Newcastle!

Despite these new coins being extremely sought after amongst collectors, the 2009 Kew Gardens 50p remains at the top of our chart, with a circulating mintage of only 210,000!

£2 Mintage Figures

After 2016, there was a 4 year period where no new £2 coins, either commemorative or definitive, entered circulation, however this changed in 2021 when 6,045,000 Britannia £2 coins were released into circulation.

The newly released figures show that in 2022, 4,030,000 Britannia £2s entered circulation, and although the amount is considerably lower than the previous year, it is indicative that there is a demand for £2 coins.

We still haven’t seen any new commemorative £2 coin designs enter circulation since 2016, however, when this does happen next, it’ll be the first to feature the King on the obverse – another collecting ‘first’!

2022 Definitives

The mintage figures for 2022 dated definitive coins were also revealed…

  • Nations of the Crown £1: 7,735,000
  • Royal Shield 20p: 42,875,000
  • Royal Shield 10p: 38,000,000
  • Royal Shield 5p: 42,800,000
  • Royal Shield 2p: 0
  • Royal Shield 1p: 30,000,000

As mentioned above, you might notice something odd about one of the denominations’ mintage figure – the Royal Shield 2p doesn’t have one! But this isn’t the first time that the 2 pence piece has had a mintage figure of zero.

No 2p coins entered circulation in 2018, 2019 or 2020, however it made a comeback in 2021 with a whopping 117,700,000 entering circulation. Despite its resurgence in 2021, it seems that the 2p drought could be returning – hopefully not for 3 years this time!


It’s always exciting when new mintage figures are revealed and you realise just how rare the change in your pocket really is!

Own a piece of the Rugby World Cup

Since the creation of the first tournament in 1987, the Rugby World Cup has served as the pinnacle of sporting excellence. As the most prestigious rugby competition in the world, to win this competition is considered the ultimate summit in rugby.

What’s more, the country that emerges triumphant not only earns the coveted title, but also etches its name in sporting history.

Therefore, it’s only fitting that a brand new 2 Euro coin is issued to pay tribute to this iconic and vastly historic sporting event.

We only have a small allocation available, so these coins won’t be around for long. Secure yours here today >>

Both new and seasoned Change Checkers will recognise the vast potential held within this coin.

Sporting coins prove time and again to be hugely popular amongst collectors, from the 2011 Olympic 50ps to newer issues such as the 2023 Manx Grand Prix £2.

The Olympic 50ps were issued in 2011 to commemorate the Olympic Games being held in London, with each 50p in the 29-coin series representing a different sport.

Still today, 12 years later, the Olympic 50ps rank as some of the most sought-after coins on our Scarcity Index.

We’ve previously seen coins issued to celebrate specific sports such as the 2022 UK FA Cup £2 for football and the 1999 UK Rugby World Cup £2 which was issued to commemorate the tournament being hosted by the UK – so it’s not the first time that the sport has been celebrated on a coin!
