ALL PRECIOUS METALS SOLD ON OUR SITE ARE TESTED WITH A SIGMA METALYTICS PRECIOUS METAL VERIFIER
The Sigma Metalytics Precious Metal Verifier operates by measuring the bulk metal comprising a bar or coin and verifies its purity percentage. Using electromagnetic waves that penetrate deeply into the coin or bar, plating and surface features are completely ignored, and the only the metal core of the coin or bar is assessed. The testing scanner can “see” through plastic cases and bags, so numismatic coins do not need to be removed from their protective cases. This assessment is completed without causing any damage or side effects at all to the coin or bar. The testing scanner can assess a sample in less than one second without affecting the coin or bullion product in any way. No chemicals are used at all and no physical damage is done during this test.
HOW IT WORKS
I select the metal that I desire to test then the testing scanner sets the value of that metal’s resistivity (a measure of the resisting power of a specified material to the flow of an electric current) to the center of the bar display. The bar display has brackets that show the expected range of the reading for the selected metal. For example, I select pure gold as the metal, and if pure gold is placed on the sensor, a value within the brackets will be obtained. Virtually any other metal with a similar weight will read far outside this range. If the actual reading does not correspond to the expected reading, an error arrow will show up on the bar display. For example, I can test Pure Gold, 22K Gold, 90% Gold and .999 Silver, Sterling Silver, 90% Silver, Britannia Silver, pure Platinum, and Palladium. Each of these coin and bullion metals will produce a unique reading on the Sigma Metalytics Precious Metal Verifier. Even very minute differences in an alloy will cause a negative reading.
