Rarest UK Coins Revealed! 2020 Mintage Figure Update

One of the biggest numismatic updates of the year comes when the latest mintage figures are announced and today we are very excited to share the updated figures for 2020 circulation coins, which have just been revealed by The Royal Mint!

As the UK’s most collected coin, it’s great to hear that three 50p designs were released into circulation last year. These include the Withdrawal from the European Union 50p, the Diversity Built Britain 50p and this year’s Royal Shield 50p.

We’ve updated the Change Checker 50p Mintage Chart with these new additions to show you which 50ps you should be looking out for:

The rarest of the trio to be released is the Withdrawal from the EU 50p, commonly known as the Brexit 50p, with a circulating mintage of 10,001,000. This is closely followed by the Diversity Built Britain 50p with a mintage of 10,300,000.

These numbers are fairly high for commemorative coins, meaning collectors stand a good chance of finding these ones in their change. What’s more, at 46,540,375 coins in circulation, we expect many collectors to be able to find the 2020 definitive Royal Shield design – just make sure you keep checking the dates on the reverse of your 50ps!

Are you lucky enough to have these in your collection? Let us know in the comments below!

2020 Withdrawal from the EU and 2020 Diversity Built Britain 50p coins

The Royal Mint’s Director of UK Currency, Mark Loveridge, said: “As the original maker of UK coins, we are delighted to play our part in celebrating the story of the nation. In 2020 two important new designs were issued on fifty pences, commemorating British diversity and the UK’s withdrawal from the European Union. Coin collecting remains a popular hobby in the UK, and finding a special design in your change adds to the excitement.”

What about the Olympic 50ps?

In 2012, the release of the Olympic 50p series kick started a collecting frenzy across the nation.

It’s estimated that around 75% of these coins have been removed from circulation by collectors which means they are incredibly sought-after, especially considering these 50ps have some of the lowest mintage figures in circulation…

Many of the Olympic 50ps have a mintage less than 2,000,000 with the rarest (the Olympic Football 50p) having a mintage of just 1,125,500. See the full mintage figures for these coins here.

Taking these rare 50ps into consideration, the 2018 Peter Rabbit and Flopsy Bunny coins would sit in joint sixth position, below the Kew Gardens, Football, Wrestling, Judo and Triathlon 50ps.

£2 Coin Update

As well as updating the 50p mintage figures, The Royal Mint also revealed that no £2 coins were issued into circulation in 2020.

There have been no new £2 coins issued into circulation since 2016, which may in part be due to the introduction of the new 12-sided £1 coin in 2017.

2016 Britannia £2

It was recently confirmed that The Royal Mint has no plans to strike any £2 coins for circulation for the next 10 years, so unfortunately, there may not be any mintage updates for this denomination for a while.

Whilst 88,071,910 1p coins were released in 2020, no 2p coins have entered circulation since 2018, perhaps suggesting it’s time we question what the future has in store for our beloved coppers.


Have you been lucky enough to find any of these coins in your change? It’s always exciting when new mintage figures are revealed and your realise just how rare the change in your pocket really is!

We’ll be updating the Change Checker Scarcity Index this month and it will be exciting to see how these new figures impact the index.

Rare Trial Pieces including Kew Gardens 50p to be Auctioned for the First Time Ever!

Have you heard the news that for the first time in its history, The Royal Mint plan to auction rare sample coins for collectors?

Trial pieces are some of the very first samples of a new coin to be struck. They are used to set the standard for each coin issued and are carefully inspected by coin makers to ensure they meet the correct standards before striking of the new design begins.

Trial Coins Put Up For Auction

Rebecca Morgan, director of collector services at the Royal Mint, said: “This month we are delighted to offer a sample of our trial pieces at auction for the first time. Each of the trial pieces has played an integral role in creating the final coin, and offer collectors the chance to own a part of numismatic history.”

The Royal Mint have announced that collectors will have the chance to get their hands on a number of trail pieces at auction on Sunday 26th September.

Included in the auction are the coveted Kew Gardens 50p (the UK’s rarest circulation coin) and the Three Graces (a collection that sold out in 25 minutes last December).

Rare Kew Gardens 50p

2009 Kew Gardens 50p

Considered the ‘holy grail’ of change collecting, the Kew Gardens 50p tops the Change Checker Scarcity Index time and again. In fact, this coin is so sought-after that collectors are willing to pay well over face value to get their hands on one, with our latest eBay Tracker revealing the coin currently selling for £157 on the secondary market!

However, we always urge buyer caution when purchasing a Kew Gardens 50p, as there are a number of fakes out there to be aware of. Find out how you can spot the fake Kew Gardens 50ps here.

1994 Mayflower £2 Trail Piece

1994 Mayflower Trial £2

Rare trial pieces have been seen before, often becoming very sought-after amongst collectors…

In 1994, ahead of the introduction of the UK’s first bi-metallic coin – the £2 – The Royal Mint created a trial piece. This was used by The Royal Mint to test the minting process of the new coin and to help the automatic vending industry re-calibrate their machines in preparation.

The trialled reverse design features a three-masted sailing ship. Although the ship is not named, it is likely to be the Mayflower, which set sail from Plymouth to America to establish the first permanent New-England colony. The outer ring bears the inscription Royal Mint Trial with the date, 1994.

There were just over 4,500 packs of this trial £2 issued and as the coin design was never released into circulation, it has become an incredibly rare example of a bi-metallic £2 coin.

If you own one of these £2 trial pieces you can consider yourself very lucky!

But with the upcoming auction set for the 26th September, we’re sure collectors will be excited at the chance of getting their hands on the trial piece coins offered by The Royal Mint, including that sought-after Kew Gardens 50p which we’re sure will be incredibly popular.

The Pioneer of Computing

Boasting an impressive career in calculus, astronomy, and arithmetics , Charles Babbage held the title of Lucasian Professor of Mathematics at Cambridge University.

The 1820s saw Babbage’s development of his ‘Difference Engine’, which was a machine that could perform mathematical calculations. Initially constructed as a six-wheeled model, it was later developed into a bigger, better, and more complex machine – Difference Engine 2.

However, his fame as a computer pioneer largely came from his invention, the Analytical Engine. It could perform any arithmetical calculation using punched cards, as well as a memory unit to store numbers – the fundamental components of today’s computers.

Babbage’s ideas were well ahead of their time, making him a perfect addition to The Royal Mint’s Innovation in Science series.

The Innovation in Science Series

This exciting series kick-started back in 2019 with the issue of the Stephen Hawking 50p.

2019 Stephen Hawking 50p

In 2019, less than a year since his death, The Royal Mint released a Stephen Hawking 50p coin, honouring his works as one of the most influential physicists of the modern age.

He became the very first person to be celebrated in The Royal Mint’s Innovators in Science series and only the third person to be commemorated on a coin within a year of their death (the others being Winston Churchill and the Queen Mother!)

The reverse of the coin, designed by Edwina Ellis, features a stylised black hole and the inscription ‘Stephen Hawking’ . It also shows the Bekenstein-Hawking formula, which describes 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.

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.

2021 John Logie Baird 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 1924transmitted recognisable human faces in 1925, and demonstrated the televising of moving objects in 1926.

Issued in 20201, to celebrate the life and works of the ‘Father of Television’, the design of this 50p coin features key milestones from Baird’s life, presented between the lines of transmission radiating from the centre of the coin.


We’re so excited to see the 2021 UK Charles Babbage 50p join the marvelous Innovation in Science series and we’re sure this brand new coin will prove incredibly popular with collectors!
