DR. DOUG'S 1-2-3 METHOD

After perfecting the magnetic slide for his own use, Dr. Doug became so impressed by its performance and utility that he decided to make this technology available to fellow coin collectors, investors, and dealers. So, he formed D-Squared Technologies to produce and sell complete testing kits in zippered carrying cases that each include, a digital weighing scale, digital calipers, a magnetic slide, and four reference coins. These reference coins are suitable for authenticating all pure silver and pure (24 karat) gold coins and bars, as well as two popular 22 karat gold investment coins, the American Gold Eagle and the Krugerrand. This equipment is suitable for coins up to 2 Troy ounces in weight.
