<p>[QUOTE=&quot;desertgem, post: 1959324, member: 15199&quot;]These USB cameras are limited. 2 mp is very old technology, especially if you are trying to&nbsp; photograph a variety, or show a complete coin. Even though this one says extended focus, you will not be able to get many complete coins in the image. Look at every usb camera under $200 and you will see their webpage doesn&#039;t show a complete coin ( sharp) larger than a nickel. Looking at the photos on CT you can tell which ones are low resolution cameras and which are regular cameras/microscopes. the background of a cent may look ok at first, but then you notice the metal field seems to have square or rectangular patterns and edges of numbers and letters may look like doubling due to the low resolution. </p><p><br /></p><p>However, if a USB like this is the most you can spend on cameras at this time, it is better than nothing, but consider it a temporary until you can get something with higher resolution and more focusing range. Also watch for software which adds details by averaging nearby pixels to increase the appearance of resolution. This can add artificial details or hide actual ones you hope for.[/QUOTE]</p><p><br /></p>
