Therefore, you can measure the diameter, thickness, and weight of the coin. To do this test at home, you will require a set of Vernier callipers and a weighing scale used by jewellers.

There is also a device called the Fisch Tester that allows you to test popular gold coins like the Krugerrand or the Gold Britannia.
