<p>[QUOTE=&quot;desertgem, post: 1949819, member: 15199&quot;]Everyone is commenting on the size, thickness, and metal purity ( all of which have an effect ( with purity difference being the lesser ) , but consider the design on the coin. They are not perfectly flat, the design acts as dampers and changes the harmonics of the tone. The maple leaf reverse device goes much closer to the rim and may act as braces to kill vibrations, and the Queens portrait on the obverse appears larger than the Kug&#039;s. It doesn&#039;t take much height above the fields to affect vibrations. Now if IDENTICAL coins with same wear or none, vibrate significantly different you may have a problem.[/QUOTE]</p><p><br /></p>
