    Ok, so when I scan any of my coins with either my HP printer/scanner or my Canon Canoscan, when i get the pic, the coins image is distorted, I mean i can see the coin, but it seems like the scanners cant process the array of colors and lighting, so edges appear as colored pixilated blocks. I have mine set on RGB so it uses the Adobe color spectrum, Setting scans between 300 and 1200 DPI and varying color and light balancing in an attempt to better the image, but still no change. Is there any way to scan but allow it to pick up details of a 3D object, or a program that would be able to do so, it should capture based on the light it sees but no coins show right. btw I use Vuescan cuz frankly it beats the **** out of any other software iv ever tried, more control. I have tried the stock apps that come bundled but no help. Help would be appreciated, also what method do you use to take pictures, trouble lighting faces of coins.

    Scanners are notorious for not picking up luster on coins and for adding bands of color to coins. These are both due to the moving light that scanners use to acquire images. I have used Visioneer scanners, years ago, and never had an issue with focus.

    When I scanned some dimes with luster, I had issues with luster not being picked up and different reflective colors being picked up that I thought be mistaken for toning. I also had an issue with a red toning not being picked up right. For coins with no luster, scanners are good since you don't have to go through the hassle of a set up.
