How much is my coin worth? June 2019 eBay Tracker update!

We’re excited to present your latest eBay Tracker and Valuation Index for the Top 10 UK coins and banknotes!

The secondary market can be a bit of a minefield, but if you’ve found a rare coin or banknote and want to work out how much it might be worth, we’ve done the hard work for you…

eBay Tracker

Find out which coins and notes have been the key movers and shakers in the updated eBay Tracker below.

The most notable increase from the last update goes (unsurprisingly) to the Kew Gardens 50p, which has increased in price on the secondary market by £5 and is currently selling for around £102 on eBay – more than 200 times its face value!

Whilst many collectors were concerned that the 2019 Brilliant Uncirculated re-issue of this 2009 coin would make it less collectable, it seems that in fact the opposite has happened and the reinvigorated hype surrounding the UK’s rarest 50p in circulation has led to an increase in demand for the coin, meaning collectors are willing to pay more to get their hands on one.

Other increases to mention are the AA01 serial number polymer banknotes, as both the £5 and £10 notes have increased by £2 since the last update, which is a 20% increase on January’s figures for the £5 and 11% for the £10 note.

Overall there has been a decrease in value for the Top 10 coins and banknotes and this is mostly due to the 2018 Sir Isaac Newton 50p, which has dropped by 32% on January’s figures and is currently selling for £40.50.

This coin was issued as a ‘Strike Your Own Coin’ from The Royal Mint Experience in 2018 and due to the short time frame it was available for, the number of coins struck could be really low, meaning it may well be very rare.

However the mintage figures for this coin haven’t been revealed by The Royal Mint yet, so we don’t know exactly how many were struck. When the official figures are released we could well see this coin increase in value on the secondary market.

My coin isn’t on the eBay Tracker

The eBay Tracker follows the movements of the Top 10 UK coins and banknotes, however if your coin doesn’t appear on the tracker you can use our 6 point guide to help determine realistic a value for your coin.

So now that you’re up to date with our latest eBay Tracker, will you be selling any of the coins in your collection or will you continue to save them? Let us know in the comments below.

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
