<p>[QUOTE=&quot;InfleXion, post: 1230819, member: 29012&quot;]I found a site showing this coin as having 0.5209 troy ounces of silver. </p><p><br /></p><p>0.5209 troy ounces * 31.1034 grams / 1 troy oz = 16.2 grams silver out of 22.5 grams </p><p><br /></p><p>16.2 / 22.5 = .720 </p><p><br /></p><p>It appears you can&#039;t really use a formula based on the purity unless the weight is also on the coin since, as in this case, it is 72% of an unlabelled weight. In cases where the weight is listed then you can just do a direct oz to gram conversion without worrying about the content. </p><p><br /></p><p>However, if you know how many ounces of silver are supposed to be in the coin you can use that to calculate the total weight based on purity. </p><p><br /></p><p>0.5209 * 31.1034768 / 0.720 = 22.5025 total grams[/QUOTE]</p><p><br /></p>
