Nice article but have you ever seen WingedLiberty's set titled the color of money?
WingedLiberty's "Color of Money" Collection
Butt Ugly IMO
don't think I'll ever understand coin grading. I went to the photograde page and checked out the lincoln cents. I can'te really see a difference between an MS61 and an MS 64 (other than the color). It is just too subtle for me. I've come up with my own 3 grades: Great, OK (I can't believe they already use "good"), and ugly.
