Very well-forged 1 oz Krugerrand, American Eagle and Maple gold coins have recently appeared. Tim Schieferstein from GoldSilberShop.de shows you how to authenticate these counterfeits. Step by step, he shows you how to carry out a visual inspection, compare the weight with the original coins, measure the original and counterfeit gold coins and identify the counterfeits based on their magnetic properties. He also explains how other professional methods of authenticity testing work, such as X-ray fluorescence analysis, ultrasound measurement or electrical conductivity measurement. The counterfeit American Eagle, Maple Leaf and Krugerrand gold coins are counterfeits with a tungsten core, which would not have been detected in an acid test or X-ray fluorescence analysis, as these test methods only examine the surface of the gold.
