Diameter of Gold Coins
The figures we give for coin diameters on this site are in millimetres (millimeters or mms), and are shown to a varying number of decimal places.
As most mathematicians and engineers would correctly guess, the accuracy of our measurements can be implied from the number of decimal places shown. All can assumed to be approximated to the nearest significant figure.
We quote dimensions and other measurements on our websites, including weights, as accurately as possible. Where possible, we take the dimensions directly from coins in our possession, but for other coins, we may have to rely on measurements from printed material, which can be less accurate.
While we are happy for you to make use of all the information published on our websites, we accept no responsibility for its accuracy, and you make use of it at your own risk.
If you note any errors or omissions, we would be delighted to hear from you.
