<p>[QUOTE=&quot;satootoko, post: 64310, member: 669&quot;]In 1982 the composition of the cent was changed from nearly pure copper&nbsp; to copper plated zinc.&nbsp; The early variety weighs 3.11g and the later variety weighs 2.5g.&nbsp; If you don&#039;t have a scale that will measure that low, just balance an &#039;82 and a pre-&#039;82 on the ends of a popsicle stick resting on a pencil.&nbsp; If they balance, you have an early &#039;82.&nbsp; If the other coin is heavier, you have a late &#039;82.</p><p><br /></p><p>There were also &quot;large date&quot; and &quot;small date&quot; varieties that year, in both compositions.&nbsp; Two Mints times two date varieties, times two compositions would be eight, but you have to subtract one because according to the Red Book there were no small date Denver copper cents.</p><p><br /></p><p>I&#039;m not that sharp on domestic stuff, so I can&#039;t tell you any way to check the dates other than just comparing two at a time until a difference is apparent. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie7" alt=":p" unselectable="on" unselectable="on" />[/QUOTE]</p><p><br /></p>
