Watch out for fake Silver coins Made in China

Watch out for fake Silver coins Made in China , there some fake Chinese pandas coins circulating , so get yourself a digital scale and weight them , the Chinese are very good in making all king of fakes including gold and silver to be very careful .Weighting could not be enough though , I am sure that there will be new fake silver with the correct weight coming soon (by mixing metals, etc). As soon as we figure out their game, they change it ,while weight is a quick and easy test. It is not a final test on whether or not it is real, There are other tests that can be done. I will have to get out the college chem textbook to review. There is a calculation based on the mass of the object and its volume displacement in water for .999 fine, this will yield a theoretical calculated weight based on the molecular weight of the metal in question. Compare this to scale , there is also the ring test where you flip the coin off your thumb to make sure your coins doesn't have a high pitched sound to it. but most importantly try to buy only and exclusively from sources you trust
