After scanning the image was rotated to correct the orientation. Contrast and density were adjusted in software. Separate images of the two sides were combined in software and a paint fill tool was used to make the background an even black.&nbsp; I never did any better with a scanner.&nbsp; Older scanners often do better than newer models and the super thin scanners never seem to do coins well.&nbsp; I really suggest you buy a camera if image quality is a factor.[/QUOTE]</p><p><br /></p>
