<p>[QUOTE=&quot;Oldhoopster, post: 7512080, member: 84179&quot;]Take it to a &quot;we buy gold&quot; or jewelry place that has a hand held XRF.&nbsp; Xrays from an XRF penetrate below the surface.&nbsp; Depth depends on a number of diff factors but if I recall correctly, it can be 100 microns or more.&nbsp; The standard plating is approx 8 microns but I would guess that a heavy plate would still be below 100 microns.</p><p><br /></p><p>A standard copper planchet has approx 5% Zinc.&nbsp; While the algorithms in the hand handheld units may not be exact for small quantities of non-precious metals, if you&#039;re seeing levels significantly higher than 5%, you have a regular copper plated cent</p><p><br /></p><p>FWIW, your coin looks copper plated to me, but that&#039;s just a gut feel looking at the pics[/QUOTE]</p><p><br /></p>
