<p>[QUOTE="rrdenarius, post: 2464747, member: 75525"]Another way to check for a plated coin is to check the weight (really the SpGr, but weight is way easier). For RR denarius, this is a pretty good, but not absolute test. Find 10 +/- a few examples and calculate the average weight and standard deviation. If you are over a couple of standard deviations low, chances are you have a fouree.[/QUOTE]</p><p><br /></p>
