Tell Me This Is Photoshop Or Focus Problems At Its Worst!

The only advantage scanning has over photography is the ability to simultaneously scan a "grid" of coins. The level of postprocessing for cropping, sizing and saving really doesn't change over camera imaging. And once you've got the process down - as I'm sure you've now realized, having joined the ranks of serious dSLR shooters - you can hit some pretty serious production rates with a camera.

It's the postprocessing that's the real hangup even if you're shooting coins of varying surfaces - you can switch settings in Zoom Browser so quickly that if you know what you need, the changeover between a lustrous MS66 Morgan and a circulated, Brown Lincoln is mere seconds. 6 minutes per coin, total, is probably pessimistic if you're really cookin'. I won't be able to help much with Photoshop, having abandoned it in 2005 or so when I switched to the Gimp, but there's a few in the Photography Forum who should be able to help.
