Here is the one silver I found - a 40%

Two 1983 and one 1984 "no FG", actually these are more like weak FG - a result of over zealous die polishing as I understand.

Three 2002 (1P, 2D), notable because of a low mintage (3.1m and 2.5m, respectively) and because they were not released for circulation, according to the Redbook - I wonder though as I have received them before.
Quite a few hole fillers for a circulated set I am assembling (my second).
That's about it except for a large number of neckline die cracks. I wrote about several of these a while ago - all 1998.

It just seems very odd to me. All in all, I found at least 20 examples, mostly 1998 and 1995. I certainly realize that these are minor hairline die cracks and they do not command a premium. But I can't think of another series, modern or otherwise, where the same general die crack is occurring over many years. You would think that some modifications would be done to the die to relieve that stress point.
