<p>[QUOTE=&quot;John Burgess, post: 7379551, member: 105098&quot;]An Ike dollar is 22.68g (+/-) 0.907 grams weight tolerance. this is not a good indicator of how much gold plating there is. </p><p><br /></p><p>Ok gold plating.</p><p>the general acceptable, gold plating thickness is 0.5 microns.</p><p><br /></p><p>12.45mg for each square inch of area gold plated to a thickness of one micron.</p><p><br /></p><p>so, this coin is 6.225mg per square inch at &quot;acceptable&quot; plating for jewelry,,, up to 1 micron thickness on the high side for industrial gold plating. </p><p><br /></p><p>1.18 square inches per side, and a little something for the edge which I don&#039;t feel like calculating. heck, lets round it up to 3 square inches of surface area.</p><p><br /></p><p>18.68mg - 37.35mg</p><p><br /></p><p>so $1.044 - $2.088 of gold plating on each Ike dollar would be a reasonable estimate.</p><p><br /></p><p>HOWEVER, they would be charging you to reclaim it, no value there to de-plate them and reclaim the gold. just not worth the effort. it&#039;s $4-$8 in total. it&#039;s got to be enough of it to justify the cost of the near pure sulfuric acid, which runs about $1200 per liter, or $1.20 per millilitre.</p><p><br /></p><p>Nobody is paying for the gold plating that&#039;s for sure. someone might save up a few tons and do a big batch reclamation, but this still isn&#039;t really worth the health and safety....</p><p><br /></p><p>And that&#039;s IF it&#039;s actually gold plating, and not fake gold to begin with.</p><p><br /></p><p>Hate to burst you&#039;re bubble, but this is the reality of it.[/QUOTE]</p><p><br /></p>
