UPDATED: The results of our latest Scarcity Index are in…

The latest Change Checker Scarcity Index update of 2018 is here and the results are in…

The 50p and £2 Scarcity Indexes have been compiled using data from the second quarter of the year.

As per our previous quarter, you can now use our new feature to help you track the performance of your coins. The arrows signify how many places, up or down, a coin has moved on the Scarcity Index; any coins with a yellow star are making their first appearance after having been released into circulation.


50p Scarcity Index


Not surprisingly, Kew Gardens still remains the most scarce UK 50p coin with a mintage figure of just 210,000. There has been a lot of movement this quarter, with significant improvements in the performance of Sir Isaac Newton, Rowing and Canoeing. 

On the other hand, both Girl Guides and Tom Kitten have seen less interest, with both coins moving 9 points down the Index.

Our top and bottom 6 coins seem to remain consistent for now, although there is always the potential for change as new coins enter circulation, and we’ve had a number of new releases recently that could mix things in up…


£2 Scarcity Index


Although the 2017 WW1 Aviation and Jane Austen £2 coins are yet to enter circulation, we’ve still seen some movement amongst the current coins in our Scarcity Index.

The ever popular Commonwealth Games Northern Ireland £2 regains its place at the top after a briefly being replaced by Wales. Another strong improvement goes to Trinity House, which has also moved up the Index 4 places.

On the other end of the spectrum, the Rugby World Cup and Florence Nightingale coins have moved down the Index this quarter, with Florence Nightingale dropping an impressive 8 places. This is due in part to a lack of Change Checkers requesting to swap these coins, however we wouldn’t be surprised to see these coins creeping up the Index in the next quarter.


What about the A to Z 10p coins?

Unfortunately, at present, there is simply not enough data to accurately compile a full A to Z 10p Scarcity Index. However, we have put together a ‘Swap Index’ using data from the Change Checker App which we feel is the most accurate way currently to determine which A-Z 10ps are most sought after.



Our top two coins (A for Angel of the North and E for English Breakfast) are very clearly the most sought after, with  L for Loch Ness Monster coming in third. Speculation as to why people might be collecting certain designs is three pronged: 1) Perhaps people are looking for A to start their collection at the beginning of the alphabet. 2) They could be looking for coins that match their initials. 3) People might be collecting the coins based on which design/theme is their favourite.


Initially, a limited stock of 2.6 million A-Z 10p coins were released into circulation through the Post Office network to coincide with the release of the designs in March. It has been no surprise that these have been quickly snapped up by eagle-eyed change collectors.

As more coins enter circulation and are found, we will begin to see more data emerge and a full Index for these coins will be compiled.


How the Scarcity Index works

Generally collectors have had to rely upon mintage figures to identify the scarcest coins.  But they only tell part of the story.  Trying to find a good quality coin from 15 – 20 years ago, even for a higher mintage issue, is much more challenging than a more recent issue, as coins become damaged over time and are ultimately removed from circulation.

Additionally, some designs are more hoarded than others by people who might not normally collect coins – the recent poignant First World War £2 Coin series being an example.  Finally, it can be up to a couple of years before the Royal Mint eventually confirms the actual mintage for an issue.

That’s why we have combined the mintage information with two other key pieces of information.

  • How many of each design are listed as “collected” by Change Checkers, indicating the relative ease of finding a particular coin.
  • The number of times a design has been requested as a swap over the previous 3 months, showing the current level of collector demand.

Importantly, as new coins are released and popularity rises and falls across different designs the Scarcity Index will be updated quarterly allowing Change Checkers to track the relative performance of the UK’s circulation coins.


How much are my coins worth?

The Scarcity Index does not necessarily equate to value but it is certainly an effective indicator.  For example, the Kew Gardens 50p coin commands a premium of up to 160 times face value on eBay.


What about £1 Coins?

The £1 Scarcity Index has already been published for the Round £1 coins and, because they are no longer being issued, this is now set in stone.


If you’re interested in coin collecting, our Change Checker web app is completely free to use and allows users to:

– Find and identify the coins in their pocket
– Collect and track the coins they have

    Hi I’m new to this but I have got a 2016 £2 coin with William Shakespeare’s name on it with a sword going through the crown. I was wondering if this is rare or collectible and if so sellable. Thanks in advance.

    • Rachel Hooper on August 28, 2018 at 8:28 am

      Hi John, welcome to the world of coin collecting! You’ve found the Shakespeare Histories £2 coin, which is part of a three coin series. As you can see from the Scarcity Index, this coin is common, but a lovely coin to add to your collection.

      You can find out more about it here: https://www.changechecker.org/coin/166/2pound-2016-Shakespeare-Histories.aspx

      Best of luck finding the next two in the series!

    Hello, I’m new to coins collection but have a 50p Olympic football. How much is it worth? Thanks

    Hi. I have a Tom Kitten 50p piece. How much might it be worth?

    • Rachel Hooper on August 7, 2018 at 8:10 am

      Hi Stephen, the Tom Kitten 50p is one of the most recent Beatrix Potter 50ps to enter circulation. These coins are sought-after because the series is so popular, however we can’t give you a figure for how much your coin would be worth as there are so many variables to consider and it all comes down to how much an individual buyer would be willing to pay. We recently posted a blog which can be helpful for determining the value of your coin: https://www.changechecker.org/2018/08/02/could-i-be-minted-the-6-point-guide-to-valuing-your-coin/ I hope this helps!

    How much is an undated 20p coin worth these days

    • Rachel Hooper on August 6, 2018 at 12:09 pm

      Typically these now sell for £40 – £50.

    Hi I am a Change Checker nut, I am constantly looking though all my change and have a huge collection of coins. My favourite coins are the commemorate £5 coins, I know you will never find one of these coins in your change but would Change Checker ever do a list of the most sort after £5 coins. Many Thanks Mr C Morgan .

    • Rachel Hooper on August 2, 2018 at 4:41 pm

      Hi Mr Morgan, thanks so much for getting in touch. It’s great to hear you’re such a keen collector of £5 coins, they really are a wonderful way to commemorate key moments in British history. A few years back we posted a blog about which £5 coins are the most sought-after, but we will definitely look at getting a new and updated blog out soon. In the meantime, here’s the older version if you are interested: https://www.changechecker.org/2016/03/11/how-rare-is-my-5-coin/
