<p>[QUOTE=&quot;mikediamond, post: 314386, member: 1859&quot;]Unfortunately, color, ring, and weight are both unreliable diagnostics when it comes to distinguishing wartime nickels struck on Cu-Ni planchets.&nbsp; Color is highly variable.&nbsp; Ring varies in wartime nickels from a bell-like tone to a dull thud.&nbsp; That probably has to do with the erratic quality of the alloy, which tends to develop microscopic cracks which dampen the ring.&nbsp; Both planchets weigh 5 grams.&nbsp; A specific gravity test would help immensely, but you need a scale that&#039;s accurate to the nearest thousandth of a gram.[/QUOTE]</p><p><br /></p>
