Welcome to the original ‘Check Your Change’. Your comprehensive guide to UK decimal coins (including all decimal coins right back to 1968).

100s of pages of information, conveniently and logically organised and smart phone friendly!

People have been checking their change with the help of ‘Check Your Change’ for 56 years! The Original Check Your Change is now online and more interactive than ever before.

In the early days it was the Pounds, Shillings and Pence that people were checking. These had served as the coinage of England, Scotland, Wales and Ireland for over 1000 years. The UK switched to a fully decimal system (i.e. 100 pennies to the pound instead of the previous 240 pennies or 20 shillings to the pound) in 1971. Forty-nine years and a good two or three generations later and anyone under 50 is unlikely to be familiar with anything other than decimal coinage.

Use this website to quickly see what decimal coins were made. The history and information behind the events. Mintage numbers with a collectability scale. Significant new issues (with the emphasis on standard coinage rather than precious metal issues) and other related decimal coins developments will be added here.
