8 Rare 50p Coins Still in Circulation – Some Worth Up to £2,367!

Since its initial release as a seven sided 50p coin in 1969, the 50p has become a highly collectible denomination of British currency. With well over a hundred commemorative designs issued throughout the decades, some of the rarer versions can fetch very high premiums within the collector’s market.

This piece takes a look at the eight most valuable and scarce 50p coins ever made by the Royal Mint, with some possibly tucked away in your loose change, forgotten collections, or lost in that long forgotten jar of coins.

1. The 2009 Kew Gardens 50p: The Crown Jewel of Circulation Coins

Just mention rare 50p coins to any British coin enthusiast, and the Kew Gardens coin will always come first on their list. First minted in 2009 to celebrate the 250th anniversary of London’s Royal Botanic Gardens, this coin has a beautiful design of the Chinese Pagoda at Kew intertwined with a patterned vine.

What gives this coin its standout value is its astoundingly low mintage total of merely 210,000 a tiny proportion of the millions of commemorative designs usually minted. For perspective, the vast majority of commemorative 50p coins have mintages measured in the millions, some more than 10 million coins.

When initially issued, Kew Gardens 50p entered circulation with minimal publicity, and most were used as normal change before it was commonly recognized as being scarce. In about 2014, as realization of its scarcity became more prevalent, prices started rising sky high.

Currently, examples in circulation can sell for £150-170, whereas flawless, uncirculated specimens can reach £250-350. The most scarce versions the silver and gold proof issues minted for collectors can bring more than £800 and £2,000, respectively, when being sold in original packaging.

“The Kew Gardens 50p is something of a numismatic legend,” says Marcus Jenkins, a London-based professional coin dealer. “Its discovery sparked interest in checking change among people who had never previously considered coin collecting. Many new collectors began their journey after learning about this coin.”

2. The 2011 Olympic Aquatics 50p: The Elusive “Error” Coin

When the Royal Mint created a set of 29 distinct 50p designs commemorating numerous Olympic sports for the London 2012 Olympics, one of them accidentally produced a sought-after rarity. The first Aquatics 50p featured a swimmer with water lines on their face, which obscured the facial features somewhat.

Once some coins had been minted, the design was altered to lower the water level so that the face of the swimmer could be easily seen. This produced two separate varieties: the “water over face” original and the more prevalent “face clear of waves” redesign.

At least only an estimated 600-800 of the original “error” version saw circulation before the change in design an incredibly minute quantity that has generated one of the most desired of modern British coins. Proof examples of the original design are valued at £800-1,300, with outstanding examples fetching nearly £2,000.

The problem for collectors is to recognize the fine distinctions between the two versions. In the rare original version, water lines unmistakably cross the swimmer’s face, whereas in the widespread redesign, water appears below the face.

This minor difference has left thousands of potential collectors searching through Olympic swimming 50p coins, although actual examples of the mistake are incredibly rare.

3. The 1992-93 EC Presidency and Single Market 50ps

Prior to the introduction of the smaller 50p in 1997, the Royal Mint produced two commemorative designs on the standard larger format to commemorate the UK’s presidency of the European Council of Ministers (1992) and the completion of the Single European Market (1993).

The first commemorative 50p coins produced very modest mintages by modern standards only 109,000 for the Presidency coin and 106,000 for the Single Market issue. Why these coins are especially valuable now is not merely that they had low mintage but timing. Issued before commemorative coin collecting had caught on as a hobby, several went into circulation without being set aside by collectors.

And then, when the 50p was downsized in 1997, many of the earlier coins were removed from circulation and destroyed. Well-preserved ones now fetch £50-70, and perfect uncirculated specimens can reach up to £120-200. Their EU-inspired designs also have an interesting historical aspect that would appeal to coin collectors and Britain’s European relationship enthusiasts alike.

“These commemorative 50p coins of the early days are a critical transition period,” comments historian and numismatist Emily Watkins.

“They were among the first commemorative designs to enter everyday circulation rather than being sold primarily to collectors, setting the stage for the explosion of commemorative circulating coins we’ve seen over the past two decades.”

4. The 2017 Sir Isaac Newton 50p: Distribution Creates Rarity

Sometimes a coin’s rarity stems not from its overall mintage but from how it was distributed. The 2017 Sir Isaac Newton 50p illustrates this phenomenon perfectly. With a combined mintage of 1.8 million, it would not ordinarily be all that rare, but instances are still notoriously hard to locate in circulation.

The explanation is the way that it was distributed. Instead of putting all of the coins out through the usual banking system, the Royal Mint put a large number of them exclusively through the gift shop at Woolsthorpe Manor, Lincolnshire—Newton’s birthplace and ancestral home.

This selective release instigated artificial rarity in normal circulation, causing naturally circulated specimens to be wonderfully valuable. The coin’s design by Aaron West beautifully integrates Newton’s revolutionary work on light and mathematical concepts, with lines symbolizing light passed through a prism and mathematical concepts from his Principia Mathematica.

Uncirculated examples usually sell for £30-55, with uncirculated specimens reaching £80-120. In spite of not technically having a very low mintage figure on paper, its atypical distribution has made it a highly sought-after collectible.

5. The 1998 NHS 50p: Growing Scarcity Through Time

Issued to celebrate the 50th anniversary of the National Health Service, the 1998 NHS 50p boasted a middling mintage figure of 5 million.

While hardly uncommon in Kew Gardens in coin terms, its historicity and antiquity have been responsible for building its worth over time as less well-preserved instances find themselves circulating in increasingly diminishing numbers.

It boasts a design showing hands placed over a heart and a stethoscope included within the digit 50. One of the first commemorative issues on the smaller 50p format, which was issued in 1997, it has become highly prized in many a collection.

Quality circulated coins are now easily sold for £10-12, with uncirculated samples commanding £25-30. Its association with the NHS—an organization of deep and abiding resonance to Britons—is just an added appeal in addition to its relative rarity.

Occasionally, a coin’s cultural value generates value as much as its mintage figures,” says Jenkins. “The NHS 50p appeals to collectors because it is about something that people care about and therefore creates demand over and above numismatic interest.”

6. The 2018 Peter Rabbit and Flopsy Bunny 50p Coins

Whereas a great number of Beatrix Potter character coins came out in significant amounts, the 2018 Peter Rabbit and Flopsy Bunny issues came out with unexpectedly small mintage amounts of 1.4 million and 1.35 million, respectively.

They are especially low in comparison to other character coins of the same series, some of which came out in amounts ranging from 8-9 million coins.

The 2018 Peter Rabbit issue (the second to include the character) features the naughty rabbit munching on pilfered carrots, while the Flopsy Bunny coin features the character clutching a bouquet of flowers. Both were created by Emma Noble and minted in cupro-nickel for circulation.

Because of their relatively low mintages, these coins now usually retail for £4-8 in circulated condition, with uncirculated specimens selling for £12-18. Although not quite reaching the exceptional values of Kew Gardens or Olympic Aquatics error coins, they are affordable rare coins with true collection and investment potential.

“The Beatrix Potter range caused a collecting mania that brought many new individuals into numismatics,” says Royal Mint Museum curator Thomas Richards. What is noteworthy about the 2018 Peter Rabbit and Flopsy Bunny coins is that their lower mintage was not generally reported at the time, meaning a lot of collectors ignored them in favor of newer character coins.”

7. The 2002 Commonwealth Games Northern Ireland 50p

Four different 50p coins were released by the Royal Mint in 2002 to commemorate the Manchester Commonwealth Games.

They all shared the same general design but with a distinctive flag for England, Scotland, Wales, and Northern Ireland. Of these, the Northern Ireland one had the smallest mintage, with around 485,500, which made it the rarest of the series.

The coin has a runner holding a baton in addition to the Northern Ireland flag. The reason this coin is so difficult for collectors is that the four variations appear quite similar upon initial inspection, with only the small flag varying between them.

As a result, numerous Northern Ireland versions found their way into circulation without individuals being aware of their relative scarcity. Today, well-preserved specimens usually command £15-20, with uncirculated ones selling for £30-50. The full set of all four countries’ coins commands an even higher premium when in similar condition.

“The Commonwealth Games coins are interesting from a collector’s point of view because they appear so similar but are so different in value,” says seasoned collector Richard Thompson. “Lots of people are not aware that they could have a rare Northern Ireland variant among their more plentiful England or Scotland coins.”

8. The 2015-16 Britannia 50p: Modern Scarcity

Completing our countdown is the 2015-16 Britannia 50p, which saw the original Britannia design return to the 50p for the first time since it was axed in 2008. With a mintage of 2.8 million, this coin is not remarkably scarce by Kew Gardens 50p standards, but it’s one of the lower mintage standard designs over the past few years.

The coin depicts Britannia in the classic stance of trident and shield, the work of Anthony Dufort. Its nostalgic imagery is popular among collectors seeking Britain’s numismatic history, and its relatively limited availability when compared to standard circulation coins has fueled growing collector demand.

Issued examples usually command £2-4, with uncirculated specimens up to £10-15. Although these prices may seem small compared with others in this list, they are a considerable premium over face value for a relatively new coin that may still turn up in everyday circulation.

Hunting Tips: Finding Rare 50p Coins

For those encouraged to seek out these coins, a few methods can enhance your success: Scrutinize other coin collections in hand. Dozens of good coins have turned up by collectors looking through coins they’d long since put into storage.

Investigate coins according to date. As some years created valuable forms, searching according to date makes it easier. Notice designs on commemorative coins. The most scarce 50p coins often come with uncommon designs instead of the usual Britannia or Royal Shield.

Ask older family members if they have coin collections or change jars. Rare coins have been found in grandparents’ old collections. Participate in coin collecting forums and clubs where members share information on recent discoveries and circulation patterns.

Authentication and Preservation

Discovery of a potentially valuable coin is only the first step. Proper authentication and preservation are important to preserve its value:

Handle coins gently, grasping them by the edges so as not to transfer oils and dirt to the principal surfaces. Keep precious discoveries in the right coin holders and not loose in jars or drawers where they can get broken.
