The Precious Metal Verifier measures the metal in a bullion bar or coin. Additionally, it makes sure that the metal matches the electrical attributes claimed. It helps to detect and prevent precious metal fraud, measure underneath the surface of coins and bars testing the interior metal. The Sigma can also assist in ascertaining the authenticity of numismatic value. And features a new measurement mode which provides a digital readout of the measured value.


The Verifier can test a sample in less than one second without affecting the coin or bullion in any way. It's chemical-free, and no physical damage is done to the coin or bullion tested. Different from other testing methods, plating and surface features do not impact the unit's ability to measure the underlying metal. The machine employs electromagnetic waves that penetrate deeply into the coin or bar. It accesses the main body of metal. The Verifier can see detect even through plastic cases and bags, so no need to remove numismatic coins from protective holders.


The user chooses the metal that he or she expects the sample is. Then, the Verifier sets the value of that metal's resistance to the bar display. The bar display contains brackets that show the range of the reading for the metal. An example: if the user selects pure gold as the metal, the user places pure gold on the sensor, a value within the brackets will show. Other metals with a similar weight will fall significantly outside of the range. If the actual reading does not match the expected reading, an arrow will come up on the bar display.


Many standard metals stow in the Precious Metal Verifier, and the user can select them. For example, for gold coins, the user selects pure gold, 22 K gold, 90% gold, or American eagle gold. And for silver: pure silver, sterling silver, 90% silver, and Britannia silver, Pure platinum, palladium, rhodium, and copper also have stored values. Each of these coin and bullion metals will produce a different reading on the Precious Metal Verifier. Even small changes in alloy make a significant difference in the readings on the Precious Metal Verifier.
