There has been much talk about grading coins and the problems that come with an imperfect system. I recall the Brown and Dunn grading guide, a book of line drawings of coins. Photograde came along in 1970, with photos of coins. Collectors could just match up their coins to the photos. Professional grading and slabs came to be in 1986. Every so often, someone mentions the possibility of computer grading. What to do?
