Sigma Metalytics Precious Metal Verifier PMV Basic Set with Case and L

The Sigma Precious Metal Verifier is specifically designed to test the authenticity of coins and bullion, although it is not typically used for testing jewelry or scrap metals. For jewelry testing, it is recommended to use the Kee Gold Tester which can be found at https://www.ebay.com/itm/122580426440.

The Precious Metal Verifier works by measuring the bulk metal in a bullion bar or coin, ensuring that the metal matches the expected electrical characteristics. It is able to assess a sample in less than one second without causing any damage to the coin or bullion being tested, as no chemicals are used during the process.

Unlike other testing methods, the Verifier is able to accurately measure the underlying metal without being affected by plating or surface features. It uses electromagnetic waves to penetrate deeply into the coin or bar, ignoring any plating or surface features and focusing on the main body of metal.

Furthermore, the Verifier is able to see through plastic cases and bags, allowing numismatic coins to be tested without having to be removed from their protective holders.
