<p>[QUOTE="Conder101, post: 4173710, member: 66"]I have found that older, cheaper, scanners will do a better job scanning coins than newer more expensive ones do. The reason is probably because scanners are designed to image a two dimensional object right on the glass. The newer or more expensive scanners do a better job of focusing right there at the surface of the glass. The older and/or cheaper scanners don't focus as precisely which gives them a greater depth of field. For a two dimensional object this isn't as good, but it does allow a BETTER image of a three dimensional object such as a coin or coin in a slab that is laying on the glass. The area in focus ranges from the surface of the glass to as much as a quarter inch above it.[/QUOTE]</p><p><br /></p>
