Thanks for the responses. I havr the 3-ring notebook that Rick has available, but it is very difficult to read, even inder my CCTV monitor, so I was truing to "simplify the info, down to one detail< (doe general grading, rather than being more accurate), thus, the one detail request. I have used the link, and it provides me a large image, with which I refer to, and have graded a tube og 1893 cents, just to test my observation, and the differences, at first were hardly noticable, but as I went thru them, I noticed I was "seeing morte detail, and began being more pricise in the separation. Out of the tube, there were two G-6 found. They both have at least three letters of "liberty"clearly visible. I intend to re sort them, to see how many change the frade! I have about a 1000 to use for the "learning process. Maybe , by that time I will have a good image in my mind to work with.
echizento, you are right, but the grade in this case will not be "fine". With at least three letters , clearly visible, it should be G-6, don't you agree?
Dick
