I suspect you may be asking the difference between a "no D" and a "weak D"?

Only the die 2 is "No D", Dies 1,3,4 can be either a "NO D" or a "Weak D" since these latter dies were most likely a combination of die wear and grease? filling of the mm area. Often on these, it is a "call" as to whether any sign of a weak MM exists. I have heard some say ,"under 5x", but I suspect it varies by the grader. Many 22 plains on ebay are "weak D" varieties. Maybe others can add to this.
