<p>[QUOTE="desertgem, post: 3365850, member: 15199"]0.6 mm is about 6 sheets of 20lb printer paper, since it surrounds the coin edge, the space on either side is only about 3 sheet thickness (0.3. I do not see how if the measurements are correct you can get a good rattle . there has to be a little space as temperature coefficients of plastic and coin metals ( silver copper, gold,etc.) are much higher than those of plastic. Many people see this with cents in plastic tubes where they are held in place by contact.. If you have a micrometer, measure the inside of the plastic and you can put a piece of electrical tape around the jaws and measure the coin without scratching it.</p><p>Jim[/QUOTE]</p><p><br /></p>
