<p>[QUOTE=&quot;SorenCoins, post: 4754874, member: 73708&quot;]Hey all. Found a nice 1968-D Lincoln memorial cent in a roll. If I am correct, the weight tolerance for copper cents (without regarding circulation wear) is 2.98g - 3.24g.</p><p><br /></p><p>I measured this cent multiple times and consistently got 2.97 grams. A few hours later, I doubled checked and it weighed around 2.96g, then I checked again and it weighed 2.98g. Obviously, a change in conditions seems to be changing the scale reading.</p><p><br /></p><p>However, 2.97 is slightly below that tolerance, and this coin has not seen much circulation, and almost certainly not enough to change its weight.</p><p><br /></p><p>I know that a hundredth of a gram is so minute that this coin is most likely not rare or valuable. How far out of the tolerance must a coin be to be considered a rolled-thin or a rolled-thick error?</p><p>[ATTACH=full]1160465[/ATTACH] [ATTACH=full]1160466[/ATTACH] </p><p>[ATTACH=full]1160467[/ATTACH] </p><p>[ATTACH=full]1160468[/ATTACH] </p><p><br /></p><p>Thanks,</p><p><br /></p><p>SorenCoins.[/QUOTE]</p><p><br /></p>
