<p>[QUOTE=&quot;Conder101, post: 2375637, member: 66&quot;]If you get 94 grams you have a clad coin or an underweight silver one.&nbsp; If you have a 99 gram weight you have a silver one or an overweight clad.&nbsp; Now from just the weights, what do you actually have?&nbsp; Weighing the coin in the slab doesn&#039;t hurt, but it may not tell you anything either.</p><p><br /></p><p>One reason this discussion started was for the possibility of detecting counterfeits by weight weighing the coins in slabs.&nbsp; So lets imagine two Morgan dollars a genuine and a fake&nbsp; that is .5 grams light&nbsp; (tolerance on a Morgan is .09 grams so our fake is well out of tolerance.)</p><p><br /></p><p>The fake in a slab could weigh between 98.4 to 100.6 grams.&nbsp; Our genuine 98.8 to 101.2 grams.&nbsp; So our well out of tolerance fake could be taken as a genuine if our observed weight is between 98.8 and 100.6 grams.&nbsp; Weighing it in the slab will only identify it as a fake if it weighs less than 98.8 grams.&nbsp; (And even then it MIGHT be a slightly out of tolerance genuine coin.)&nbsp; Since most every weighed slabbed silver dollar will weigh in that range, weight of a coin in the slab will seldom be able to tell you if a coin is real or fake.[/QUOTE]</p><p><br /></p>
