Looking through some 1958 D LWC's I found 11 with the same die cracks on the obverse and reverse. There is a crack on the head that stops just short of becoming a "spike head". And there is a crack along the length of the left-hand wheat stalk. I put one example complete and then another example. They are all very much the same on all 11 coins.
Nice die pair match up. Thats a good % for one roll. Do any show crack progression? I found four die matching 1970-S in a roll. I matched them by die cleaning that left raised line on the surface of the coins. Fun stuff. I got 4 crack heads from a 1957 roll. more fun stuff.
There was some progression, but not enough to be significant. I found 7 in this roll with a different crack and a matching die marker on the reverse. The die crack was more horizontal. I will show below a shot of the crack and of the marker. It is a small die scratch or polish mark that comes off the inside bottom of the left wheat stalk.
Hope you don't mind if I post photos. Note die chip in 'S' and small incuse mark protruding from the back of the seven. Scratched die lines above '7'.
