<p>[QUOTE=&quot;gatzdon, post: 223317, member: 8247&quot;]The mint spec for the diameter of the coin is 1.043 inches +/- 0.003 inches.&nbsp; This is a very tight spec and removal of the edge lettering requires the removal of more than 0.006 inches worth of material.&nbsp; This should be the first test for authenticity that anyone performs.&nbsp; This test should be followed up with visual inspection for evidence of plating or any other means of Adding material back to the coin to restore the diameter (including flattening the coin).</p><p><br /></p><p>Short of measuring the diameter accurately, one is taking a risk when buying these coins.&nbsp; The only time one should consider that risk is if they personally know the source of the coins.&nbsp; Obviously a reputable third party grading service also goes a long way and that&#039;s why slabbed coins can command a certain premium (of course that last sentence was preaching to the choir)</p><p><br /></p><p>One cannot go by weight under any circumstances.&nbsp; the spec for the weight is 8.1g +/- 0.3g.&nbsp; It has been shown repeatedly that the edge lettering can be removed with less than 0.3g of material.&nbsp; All a fraudster has to do is start with heavy planchets as they are sufficiently abundant.[/QUOTE]</p><p><br /></p>
