<p>[QUOTE=&quot;desertgem, post: 8285207, member: 15199&quot;]This image compares to your # 4 photo, it is a 69S cent and it is considered mechanical doubling since the underlying images have a flat sheared surface. If you have access to the microscope, you can slowly focus up and down and see if each doubling is rounded ( RPM) or flat (damage).</p><p>A flat surface goes quickly in/out of focus with vertical movement, rounded goes in/out gradually.</p><p>Good Luck, Jim[ATTACH=full]1463640[/ATTACH][/QUOTE]</p><p><br /></p>
