The Best Fake Gold Coin Detection Tool

Other metals used to create fake gold coins can not match a genuine Gold Coin in size and weight. For example, Gold is heavier than lead by 30%. A coin made of lead would have to be bigger in size by about 1/3 to weigh what a gold coin weighs, so a lead coin would not pass either the size or the weight test.
