I scan at 300 to 400 and the pic size ends up 60K to 250K depending on the size of the coin. I have over 1400 coins scanned so you can see what I mean about storage. My better coins will be photographed, as soon as I get a Camera. Report this Post to the Staff

Some provide really nice results at 1200dpi; others aren't a whole lot of use over 600dpi. My Epson is starting to blur details at 1200dpi, so I scan at 600. With that said, at 600dpi a Morgan dollar is 900px in diameter on your screen, quite a bit larger than necessary for accurate representation. So, I'd recommend that you play with your individual setup. If you find it to give accurate results at 1200dpi, then use this setting for smaller coins and back it down somewhat for the larger ones. The goal is a nice accurate representation at a resolution which is usable in the real world; scans are going to be observed on computer monitors, so your results should look good on computer monitors. If you can create a good clear image of about 650-700px for a given coin, you're succeeding. For a dime, this would be approximately 900dpi. Report this Post to the Staff
