Abstract
Throughout the world, there is growing trend by investors to protect wealth by holding silver and gold coins and bars. Unfortunately, there are also a growing number of counterfeit coins and bars coming into in circulation. This situation cries out for an affordable method that can be used by untrained investors to quickly and reliably discriminate authentic coins and bars from counterfeit ones without causing damage to their coins and bars. The disclosed method fills this need by the use of a combination of conventional and novel designed pieces of equipment for measuring the following three characteristics of a coin; (1) size, (2) weight, and (3) relative terminal velocity on a magnetic slide. The results of these measurements can be used to unambiguously discriminate pure silver and pure gold investment coins and bars from counterfeit ones and can also be helpful in evaluating 22-karat gold coins and pure platinum coins.
