<p>[QUOTE="rmpsrpms, post: 2929241, member: 31773"]Folks often ask about magnification and what is needed for showing varieties well. They get confused by the magnifications claimed for USB microscopes. Those scopes often state 100x or even 500x magnifications, but these are not optical magnifications. They include the digital magnification of "projecting" the digital image from the camera sensor to the monitor/display, which has much larger pixels than the camera. In reality, for coins, I find that 5x is a great starting point, and can show the full date/mintmark of a Lincoln Cent. I call this the "money shot". 10x can zoom-in to show the mintmark in more detail. 20x is about the highest magnification I would consider using for coins, and can show details of the mintmark itself. Here is a 1954-S RPM#4, taken at 20x to show the RPM in more detail:</p><p><br /></p><p>[ATTACH=full]710886[/ATTACH][/QUOTE]</p><p><br /></p>
