Coin & Bullion Tester
Gold Lock’s Gold Tester (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. These Gold Testers will protect you from being ripped off by letting you see the frauds.
