Patented Technology Detects Tungsten!

Every metal, including Gold and Silver, has unique magnetic properties. The Gold Lock’s patented technology capitalizes on this phenomena to detect tungsten hidden within gold and silver.

The Gold Lock Internal Tester

Gold Lock’s Internal Coin and Bullion Testers (US Patent #9,934,639) protects you from fake coins and bullion that are nothing more than gold plated tungsten.  No other test for tungsten is this simple or fool proof.  Simply insert the coin into the Tester and use the activator to illuminate tungsten or other anomalies concealed inside the coin.  The Internal Coin Tester and Internal Bullion Tester will protect you from being ripped off by letting you see the frauds.
