<p>[QUOTE=&quot;buyingsilvers, post: 1313242, member: 18821&quot;]thickness is the hardest dimension to measure.&nbsp; I believe that technically, you&#039;re supposed to be measuring the rim.&nbsp; If the edge of your calipers are inside the rim, you&#039;ll get a different reading.&nbsp; Also, there tends to be variance in rim thickness from the minting process.&nbsp; Also, you&#039;re not supposed to squeeze the coin in the calipers or you&#039;ll get a different reading.&nbsp; </p><p><br /></p><p>I wouldn&#039;t worry unless one of the parameters is grossly off.&nbsp; Also for gold and platinum, usually the only time you need to be concerned is if the coin is bigger, not smaller.&nbsp; Say you measured the thickness, and it was 3 mm instead of 1.4mm.&nbsp; There aren&#039;t many metals that can be used to fake gold and platinum that are denser.&nbsp; Commonly used metals such as copper, nickel, iron are all less dense, and one of the attributes (weight, diameter, thickness) would be way off.[/QUOTE]</p><p><br /></p>
