Perform a magnetic test Gold is a precious metal that is not exposed to magnetic forces. Coins that contain a high concentration of gold therefore do not react during a magnetic test. This test is an easy way to identify counterfeit gold coins, as they often contain inexpensive metals that are magnetized. The acid test is usually used to test gold jewelry.
However, it can also be used to test coins and bars to verify authenticity and the stated purity. For each degree of fineness, a specific test acid is used, which is applied to the mark created when the golden (or gold-colored) test object is rubbed on a dark stone. If the mark fades when in contact with the acid, there is a high probability that the gold that left the mark is incorrect. It should be noted that this method of authentication only tests the surface of an object.
The acid test does not recognize whether an item is simply gold-plated. If the gold coin looks different than the one that is real and authentic, it means that it is a fake gold coin. Counterfeit gold can be available in the form of coins or gold bars, which contain different grades of gold or gold with a lower degree of purity than stated. Tungsten bars coated with real gold are particularly deceptive in appearance and weight, as their density is almost identical to gold.
These marks indicate that only a small percentage of gold was used to cover the coin from another metal and not gold. Gold is denser than most metals and so this test works pretty well, particularly with gold coins and gold bars. It’s also safest to opt for trustworthy banks and other financial institutions, such as Muthoot Gold Bullion Corporation, which make it easy for you to easily buy pure and authentic gold coins online.
