The Precious Metal Verifier, or PMV, uses patented technology to rapidly and non-destructively test precious metal coins and bars for authenticity. PMVs can quickly and accurately assess a wide range of samples with just a few button presses. There's no chemicals, no complicated calibration, and no ongoing maintenance needed.

Sigma Metalytics' patented technology tests the characteristic resistivity of a sample and determines if the sample's resistivity is consistent or inconsistent with the selected alloy. Additionally, the PRO, Mini, and Investor models can also test the density of the sample to ensure correct specific gravity of the sample.

Join the thousands of professionals, hobbyists, and investors across the precious metal industry rely on Sigma Metalytics PMVs every day to keep their businesses, investments, and collections safe from counterfeit coins and bars. Private collectors, mom-and-pop coin shops, major bullion dealers, and folks in between trust their PMVs to get the job done.
