<p>[QUOTE=&quot;Conder101, post: 735013, member: 66&quot;]Yes, but what he is really asking about standard sizes is do all PCGS slabs for cents weiht the same,do all PCGS slabs for dimes weigh the same, do all PCGS slabs for nickels. . .&nbsp; and so on.&nbsp; That way if you have a given coin and you know whatthe weight of the slab should be for that denomination should be, could you weigh the slabbed coin and subtract the weight of the slab to determine the weight of the coin and use that fro an authentication test.&nbsp; The answer is no.</p><p><br /></p><p>What everyone likes to forget are tolerance ranges.&nbsp; Well I&#039;m sure the weight of the slabs have tolerance ranges as well and I would bet they are not as precise as the ranges for the coins. (And the ranges for some coins a fairly loose)</p><p><br /></p><p>If you are weighing a coin in a slab that has a .1 gram tolerance say a copper Lincoln cent, and the slab has a 10 gram weight with a .5 gram tolerance, then a genuine weight could range anywhere from 12.5 grams to 13.7 grams.&nbsp; A variation of 1.2 grams or almost half the weight of the coin you are weighing.&nbsp; Say you have a fake cent that only weighs 2.5 grams way below tolerance for the cent, but it is in a heavy slab.&nbsp; 2.5 gram coin plus 10.5 gram slab gives a weight of 13 grams.&nbsp; Well within the range for a genuine slab and coin weight.[/QUOTE]</p><p><br /></p>
