<p>[QUOTE=&quot;Bill in Burl, post: 1382983, member: 23692&quot;]As I said before, specific gravity will tell you nothing if the coins have the same dimensions and weigh the same .... mass with respect to volume and water, that&#039;s the definition of specific gravity.&nbsp; An electron scope or zapper will tell in a heartbeat.&nbsp; We should have an article soon in the CN Journal about zapping hundreds of 1859 cents to try to demystify the brass quandry.&nbsp; Higher silver content will produce a sharper higher pitch sound when dropped .. I&#039;ve heard hundreds of silver dimes, quarters and halves hit the bar.[/QUOTE]</p><p><br /></p>
