<p>[QUOTE=&quot;jlblonde, post: 2805389, member: 32000&quot;]When scanned, copper and bronze coins will almost always have dust particles that appear in the images and will be darker over all.</p><p><br /></p><p>Try the following:</p><ol> <li>Use a small air compressor or a can of compressed air to remove the dust from the coin and the 2x2 before sealing the coin in the holder.</li> <li>Use a bottle/can of glass cleaner or lens cleaner and a specialized lens or guitar rag to wipe up the scanner and the outer window part of the holder.</li> <li>Scanner settings need to be adjusted for each coin:</li> </ol><p> <ul> <li>Image Type: 24 bit color or better</li> <li>Resolution: 400 to 800 dpi</li> <li>Auto Exposure: Photo</li> <li>Adjustments: Select &quot;Unsharp Mask&quot; and level &quot;High&quot;</li> <li>Image Adjustment: Move &quot;Brightness&quot; and &quot;Saturation&quot; to desired levels.</li> </ul><p>This is the method I use for scanning coins images. I have a cheap Epson 420 printer/scanner. Unfortunately, some proof and toned coins cannot be scanned to show off their brilliance or toning. For this, I would suggest a micro scope with photo capturing. They can be had on the cheap and do a decent job simply for posting and examining.</p><p><br /></p><p>Hope this helps.[/QUOTE]</p><p><br /></p>
