I've struggled to take nice, clear photos of coins. Silver coins seem especially dificult. They can quickly become mirrors. I'm now using a Nikon Coolpix. For close-ups I have rigged up a device to use my OLD binocular microscope. It invloves the macro setting on my camera and a toilet paper tube. Don't laugh it works pretty well. Here's a photo of my set-up less camera and an example of what it can do on a Morgan Dollar. The black spot is an artifact of the microscope. Like I said, it's old.
