<p>[QUOTE=&quot;GDJMSP, post: 2738365, member: 112&quot;]Yes wear can have an effect on the weight of a coin, but rarely does wear have any appreciable effect on the weight of a coin until the wear reaches the VG to G grade or lower. In VG weight loss will vary but is still typically minimal. IN G and lower the weight loss numbers increase. </p><p><br /></p><p>But with the coin you&#039;ve pictured at 26.28, I believe you are right to be suspect for there is no way it would have lost that much weight given its condition. Even accounting for the tolerance from the mint at at its maximum of 0.097, (assuming Jim is correct) the coin should still weigh at least 26.60 gm.</p><p><br /></p><p>Even understanding that there&#039;s still several possibilities. The coin may be fake, your scale may be inaccurate, your scale may need to be calibrated. So you still don&#039;t know anything definitive.</p><p><br /></p><p>You mentioned that you weighed a BU Morgan and it showed 26.73. And that may well be an accurate weight, but it could also be off quite a bit. I say that because given the mint&#039;s weight tolerance, any BU coin could weigh anywhere from 26.633 to 26.827 and be quite genuine. And that&#039;s a difference of almost 2 tenths of a gram - for a BU coin.</p><p><br /></p><p>But to get to the numbers you&#039;re talking about, 26.28 and 26.19, those are differences of half a gram, or more. And that is unlikely even given wear, unless the coin is worn almost slick.</p><p><br /></p><p>To help you understand what I&#039;m talking about take a look at this coin.</p><p><br /></p><p>[ATTACH=full]624710[/ATTACH] [ATTACH=full]624711[/ATTACH] </p><p><br /></p><p><br /></p><p>Even worn that much, (I would grade it no better than F15) that coin only lost 0.003 of a gram in weight. And that&#039;s actual lost weight from what the coin weighed when I got it.</p><p><br /></p><p>So do you see what I mean ? </p><p><br /></p><p>Now if you don&#039;t have a calibration weight for your scale to test the scale itself, take the coin to a jeweler and ask them to weigh it for you, to at least 2 decimal points. Then compare that number to what your scale says. That will tell you if your scale is off or not. I&#039;m not saying it is, I&#039;m just saying it&#039;s possible it is.[/QUOTE]</p><p><br /></p>
