<p>[QUOTE=&quot;cladking, post: 580655, member: 68&quot;]Well, the thickness of a clad dime is more variable than an old </p><p>silver dime.&nbsp; Weight is determined by the thickness (and compo-</p><p>sition) of the strip from which the planchet is punched.&nbsp; This </p><p>thickness has not changed for dimes since the 1850&#039;s if mem-</p><p>ory serves.&nbsp; (it decreased 1% for quarters in 1999).</p><p><br /></p><p>Thickness of a coin is determined primarily by design and strik-</p><p>ing characteristics but also by planchet thickness and upset-</p><p>ting characteristics.&nbsp; Clad dimes can be very thin where they</p><p>are struck with low designs and lightly upset. (rolled between </p><p>two rollers to reduce diameter of planchet)&nbsp; Such coins tend </p><p>to have low rims like the 1999 issues.&nbsp; Other dates can be much</p><p>thicker.&nbsp; Proof dimes can be 10% thicker on average than BU </p><p>examples.&nbsp; </p><p><br /></p><p>Even within the same date there can be substantial variation.&nbsp; </p><p>Generally poor strikes mean thinner coins but even this isn&#039;t a</p><p>given I believe.&nbsp; </p><p><br /></p><p>Most modern coins have significant changes from year to year </p><p>and some of these changes do result in thickness variability.&nbsp; </p><p>Clads aren&#039;t made to as exacting standards as pre-1950 coins</p><p>and this increases variability as well.&nbsp; Quality has been improv-</p><p>ing in the past decade and much of this has been at the expense</p><p>of relief (which also affects thickness).[/QUOTE]</p><p><br /></p>
