<p>[QUOTE=&quot;Conder101, post: 212615, member: 66&quot;]If you are going to measure the diameter do it in mm NOT inches.&nbsp; Especially if your caliper only goes to two decimal places.&nbsp; The difference shown in the first post was .01 inches which doesn&#039;t sound like much.&nbsp; Until you compare it to mm and against the tolerances.&nbsp; .01 inches is .25 (rounded to two places) mm and the tolerance in the diameter is .003 inches or .08 mm.&nbsp; The original size he showed of 1.04 inches is 26.49 mm.&nbsp; Spec is 26.5 a difference of .01 mm.&nbsp; the .01 inch decrease in diameter is as I said .25 mm or a little more than THREE TIMES the legal mint tolerance.&nbsp; That is a BIG discrepancy.&nbsp; </p><p><br /></p><p>Also examine the edge under a loupe.&nbsp; A genuine smoothie will have a multitude of vertical lines of differing lengths on the edge.&nbsp; These are remnants of the shear edge from the blanking, and ejection scratches from being forced out of the collar after striking.&nbsp; The areas that don&#039;t show the lines will show the flat smooth appearance of metal forced against the flat collar.&nbsp; Both of these are removed in a grinding, buffing or milling procedure.&nbsp; Typically those processes willl leave tool marks that run horizontally around the coin and not vertically across the coin.&nbsp; another feature is the shape of the edge itself.&nbsp; On a genuine smoothie there is a flat on the edge and then bevels top and bottom from the flat to the rims.&nbsp; The flat is cuase by the expantion of the coin against the collar, but the pressure usually isn&#039;t enough to form the edge completely so you get the bevels.&nbsp; When the coin is compresses in the lettering die it also squares up the edge some more.&nbsp; Also if someone sands off the lettering the edge will usually be rounded and not show the flat area.&nbsp; If it is milled it will usually be very squared off and not show the bevels unless the machinest knows enough to put them back on.</p><p><br /></p><p>A real good way to learn what the edge of a genuine smnoothie would look like is to closely examine the edge of a new Sac dollar.&nbsp; Look at the shape, the surfaces and the characteristic scratches.&nbsp; Once you know what a genuine edge looks like you should not be fooled by a home made fake.[/QUOTE]</p><p><br /></p>
