UPDATED: The Change Checker Ebay Tracker

With more and more UK coins (and recently banknotes) being released and an ever increasing international interest in coin collecting, it can be difficult to keep track of how much the most sought-after coins are fetching on the secondary market.

In order to help you, we are delighted to share our UPDATED Change Checker eBay Tracker and Valuation Index for the Top 10 coins and banknotes!

After a small rise in value in January 2018 across the 10 tracked issues, it’s very interesting to see that there has now been a general decrease in prices,with only 2 of the top 10 seeing an increase in the price they have sold for. As you can see in the tracker below, the Jemima Puddle-duck 50p has had a significant effect on the overall value, effectively putting a cap on the maximum value able to be achieved currently.

The most surprising change to see between January and June 2018 is that the AA01 serial numbered £5 polymer bank notes are now selling for £14.50 – £4 higher than before. It would appear that the urge to get hold of one of these early printed notes is still very much present. Have you managed to get hold of one and if so, are you planning to sell it on?

The biggest decrease can be seen with the undated error 20p coins, seeing a £7 decrease from £53 to £46. As we know, up to 250,000 of these coins made it into circulation so it could be that more coins are being found now that more collectors know what to look for.

Undated 20p selling for £46

The undated 20p is regarded by many as the Holy Grail of change collecting, becoming the first coin in over 300 years to enter circulation without a date and I’m sure you’ll agree that £46 is still not a bad return for a 20p coin!

So even though we can see a general decrease in value between January and June, the overall value is still strong with the 8 tracked coins showing a 36x premium over face value!

Not surprisingly, the highly sought-after Kew Gardens 50p remains king, selling for £80.50, with some in good condition still selling for over £100! These coins are definitely worth keeping an eye out for.

And due to the large amount of hype surrounding the new Paddington 50p coins, we expect them to become a potential top 10 contender in the near future. It’s a very exciting time to be a change checker, as we are sure that these coins will be extremely collectable.

Let us know in the comments below if you’ve managed to find one of these scarce coins in your change or if you’ve sold on any coins for more than face value.

How does the eBay Tracker work?

The Change Checker eBay Tracker takes the last 9 sold prices achieved on eBay and gives the median price achieved (rounded to the nearest 50p). By taking the median, rather than an average, we avoid skewing created by one or two excessive prices achieved.

Please note that the Change Checker eBay Tracker is only ever designed to be a guide as to prices achieved on eBay. Prices may vary depending on collector demand and the quality of the coin being sold. It does not provide any guarantee as to future values of coins.

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
– Swap their spare coins with other Change Checkers

    Besides e-bay is there anywhere where you can take your coins.
    I’ve been saving 50p and £2 coins to spend and just gone through them and have a variety of both coins.
    All new to this looking for coins

      Hi Sue, you can use the Change Checker swap centre to swap coins with like minded collectors and build up your collection. If you’re looking to sell your coins I would suggest taking a look on the British Numismatics Trade Association website. Best of luck!

    There are a lot of “Copy” Kew Garden Coins around, they sell for around £5 on e-bay.
    They are easy to spot as they have the word “COPY” just under the Queen’s Head in very small letters.
    Ideal to show in a collection but not as good as the REAL THING!
    I have couple of “Fakes” but two genuine ones which do not see the light of day!!

    I started collecting 50p coin as a hobby but soon realised I needed help so now have my local barmaids and girls in bookmakers collecting.
    Decided we will give proceeds to charity when we have decent collection to sell.
    Currently have 40 out of top 54 on one list we have so what would our best option be to sell them when we are ready?

    • Rachel Hooper on July 2, 2018 at 11:26 am

      Hi Ian, it sounds like you and your team have built quite the collection, fantastic work! I would suggest looking on the British Numismatics Trade Association website when you are ready to sell. Best of luck to you guys.

    Can I just ask if JPD was originally said to be 2.1 million… Has the re-release of it made much difference to that total ??

    • Rachel Hooper on July 2, 2018 at 1:16 pm

      Hi Stephen, only 2.1 million Jemima Puddle Duck 50ps were actually. released into circulation. Thanks, Rachel

    Just read the comments & Clive I have often thought that for saying there is not so many Kew Garden’s coin’s It does make you wonder if they are fake’s.I have 1,but when you have a look on eBay there is a lot of Kew Garden’s and it does make you wonder if they are real or not.Thought this many time’s myself.

    • Clive Morris on June 28, 2018 at 4:32 pm

      I have two Kew Gardens 50p – one mint in the 2009 annual set purchased from the Royal Mint so I am sure that is real. The other which is in my circulated 50p collection I could not be 100% certain about, although it does not have any of the reported errors the fakes have

  6. kayleigh roberts on June 28, 2018 at 9:01 am

    I’ve got two Jemima puddleduck 50p I will be keeping them with my collection just too think how much they could be worth when iam 90 and passed down to my children

    • Rachel Hooper on June 28, 2018 at 9:27 am

      What a great find Kayleigh! And a great idea to pass them on to your children.

  7. Anthony Davies on June 27, 2018 at 5:57 pm

    I have picked up pre 92/93 EEC 50 pence coin
    For £45 mint condition because it was encapsulated in clear resin before it was used and made into a paper weight (just need to extract it when I am ready)

  8. Roger Charlesworth on June 27, 2018 at 3:42 pm

    What is the point of a price tracker? Just look at JPD : it got up to double figures because the RM ONLY minted 2M compared to 10M for Peter Rabbit. So TWO YEARS LATER they REMINT JPD with STILL a 2016 date!!!!! Bonkers, or worse.

    Why not REMINT Kews if you can remint JPD’s. THAT may have an effect on their price don’t ya think?

    In effect the RM is in TOTAL control of price because it can mint as few or as many as it like.

    The RM have just turned this whole subject into a FARCE

    • Rachel Hooper on June 28, 2018 at 9:33 am

      Hi Roger, the re-minting of coins can be very frustrating for collectors. Regardless, there will always be those few such as the Jemima Puddle Duck and Kew Gardens that always seem to be on top and act as a cap for the price of other coins.

  9. Clive Morris on June 27, 2018 at 2:46 pm

    I wonder how many of the coins sold on ebay are fakes

    • Rachel Hooper on June 28, 2018 at 9:29 am

      It’s always the risk with eBay unfortunately Clive.
