Weights Quoted for Gold Coins
The figures we give for the gross weight of coins on this site are in normally in grams (gms), and are shown to a varying number of decimal places.
Most modern scales are calibrated in grams, so this is often the most convenient scale to use.
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.
The figures shown may be the actual, declared, specified weights, or may be those found by physical weighing. Manufacturing tolerances apply to all coins. Wear and tear will slightly reduce the actual weight of most coins which have been in circulation.
AGW = Actual Gold Weight
In line with Krause, we usually quote the actual fine gold content of most coins in troy ounces. The price per troy ounce is the most widely quoted price for precious metals.
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.
