<p>[QUOTE=&quot;GDJMSP, post: 965439, member: 112&quot;]Jim&#039;s idea would probably work. Small problem with it though. These coin holders are not manufactured with high precision so it is quite likely that there can be differences in tightness of fit from 1 to another. So the the test would need to be done with several holders in order for it to be a viable test.</p><p><br /></p><p>Of course there is another possible outcome than the one expected by most. Consider if you will, when brand new there are microscopic bumps, roughness on the portions of the holder that touch each other. It is this roughness that seemingly makes the 2 halves harder to put together or take apart the first time. </p><p><br /></p><p>But - with a little use (2 or 3 openings and closings) that roughness is smoothed away which actually increases the tightness of the fit providing a better seal than when it was brand new. </p><p><br /></p><p>Didn&#039;t think of that did ya Thad ? <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie8" alt=":D" unselectable="on" unselectable="on" />[/QUOTE]</p><p><br /></p>
