<p>[QUOTE=&quot;rlm&#039;s cents, post: 828941, member: 7957&quot;]Yes, your idea will work, but I do not think as well as you think it will.&nbsp; I do not think you will find copper that much more reactive so it will do a good job of preferentially removing the contaminants - most particularly with other coppers.&nbsp; However, a couple suggestions might help.&nbsp; I believe you will find zinc a lot more reactive than copper.&nbsp; That can be employed either by using pre-1982 cents (minor help) or, better, post-1982 cent cores.&nbsp; Other metals (iron comes to mind) might even be better.&nbsp; Another improvement would be to increase the reactive area of the sacrificial metal.&nbsp; Powder being best (but most dangerous).&nbsp; Elongated pennies, etc. would help.[/QUOTE]</p><p><br /></p>
