Silver Bar Testing to Avoid Counterfeits and Partial Fakes

A careful perusal of Ebay makes it quite evident that there are many fake silver bars floating on the market.  Chinese made fake precious metal coins and bars are being sold on on the internet.  Obviously buying from a reputable vendor is a good idea.  Even if you buy from a reputable vendor what if they have been gamed successfully?  They would have a set of tests that any reasonably good engineer could probably design a product that would fool them. It pays to be able to spot the real thing yourself.
