Scanner No?

Scanner why not? They produce perfectly clear pictures for posting purposes, excepting the lack of ability to show luster. Keep the sensitivity to 600dpi or less for posting whole-coin pics; 300dpi will do. Remember, very few of us are looking at these pics with a monitor which will show more than 100dpi. That keeps file size down. A clear scan of a coin which is 650 pixels in diameter is enough to come up with a tentative grade and firm attribution of a Bust Half.
