<p>[QUOTE=&quot;-jeffB, post: 3296476, member: 27832&quot;]I&#039;d say the specific gravity test is probably useless for that coin, because there&#039;s no reason to think it would be made from the wrong metal.</p><p><br /></p><p>It makes sense for counterfeiters to use base metals (almost always less dense) for fake silver or gold coins. It would make <i>no</i> sense for them to use anything other than the right alloy for a fake copper cent. It&#039;s easy enough to get a bunch of old cents and melt them; it&#039;s just as easy to make the alloy from its components.</p><p><br /></p><p>It&#039;s <i>possible</i> that the coin would have the wrong specific gravity, but it&#039;s <i>extremely unlikely</i>, IMHO.</p><p><br /></p><p>The specific-gravity test is also hard to do well -- tiny errors in weight turn into large errors in specific gravity. You&#039;d find it very challenging to measure it within 1%, which is about the weight difference you found.[/QUOTE]</p><p><br /></p>
