The App

Huge March 2024 APP UPDATE with hundreds of value changes – Rolling out now!

The October 2023 update is the most recent version and has been rolled out for both Android and iOS. As ever, it includes a lot of changes. Info log of changes, here.

The current version now includes all of the non circulation decimal coins, half penny to £5 and the ability to mark different quantities of ‘used’ or ‘as-new’ coins.

The original UK coin app with valuation data! – The Check Your Change decimal UK coin app was the first app available which included the option of viewing coin valuation data….and with over 800 different coins, it’s still the most comprehensive.

Some Frequently asked questions relating to the app, click this line.

The Check You Change UK coin App allows you to view all information for current circulating UK coins*. As standard you can toggle coins as ‘got’ or needed and use the colour-coded view to easily show what coins you need and which you already have. You can also save a short text note for each coin, e.g. to keep a note of the condition, what you paid for the coin or where you found it etc.

Some screenshots, explanation and features (on an early release, newer versions have slight changes):

Image 1: One of the main denomination pages. Swipe up or down to show earlier/later dates. Note the top left green box shows the number of coins out of the grand total of possible coins to own. The ‘All’, ‘Need’ and ‘Got’ options filter the coins so that it’s easier to see all coins or the coins you need or already have. Coins with a light red background (all of them in this image) are coins that are needed. When marked as ‘got’ the backgrounds change to light green. Coins that were originally only available to purchase have a three-circle icon bottom left, e.g. the first 2009 coin in the top row.  Based on the current market value/demand, some coins have a crown icon (top right) and are accompanied by either a bronze, silver or gold coloured border.

Image 2: One of the main coin pages showing the 2010 Mary Rose £2 coin. Top right is the ‘Notes’ feature icon (see image 6). The mintage numbers of every coin are shown, as are edge motto details where relevant, a short title and a longer description which usually includes the designer name. The ‘Got it’ logo is greyed out until pressed, upon which it will turn green and the coin is marked as owned. The red arrows are for moving chronologically through the range of coins. If the premium version is not purchased the ‘UNLOCK PREMIUM FOR VALUATIONS’ if shown above the ‘Back’ button.

Image 3: Another of the main individual coin pages, in this case for the 2010 Belfast city £1 coin. This one has been upgraded and shows the value of the coin in used condition (in this case it’s FV for face value) and in as-new condition (correct 7/3/17).

Image 4: Another main coin page, again showing the Mary Rose £2 coin but this time with the premium values turned on.

Image 5: When any of the coin images of the individual coin pages are pressed they reveal a larger image of the coin, which is handy to clarify identification. This example is the 2002 Northern Ireland Commonwealth Games £2 coin.

Image 6: An example of the notes feature. Up to 256 characters can be recorded for each coin. Very handy for noting all kinds of information.
