<p>[QUOTE=&quot;desertgem, post: 1770154, member: 15199&quot;]75% copper (metallurgic wise) differs significantly in characteristics from 95% copper. Yes, they are both copper alloys, but the Ni gives a very different set of characteristics due to the molecular structure. And now you have me confused, are you saying that Nic-A-Date should work on 95% copper cents? I do not believe so.&nbsp; And Jallen I must respectfully disagree with the metal flow. As far as discernible, I guess I can&#039;t argue as I am unsure of the actual amount of flow movement.[/QUOTE]</p><p><br /></p>
