1972 MisAligned dies - Die knowledge

[jupiterkm1]

I'm trying to expand my die knowledge from the Forum's Glossary (a superb glossary it is!). I have a roll of 72 Red's, where perhaps 70-80% of the coins have an obverse misaligned die punch, the reverse mush less so, if any at all. I originally thought they were off-center strikes, but the Glossary corrected me.
I noticed the coins are noticeably "thinner" where the mis-alignment comes closest to the rim. How does the hammer die mis-alignment create the thinness if the planchet is still bound by the collar? I tried to think 3 dimensional, but the only theory I could come up with is the hammer die is mis-aligned "east/west" (horizontal) as well as "north/south" (verticle). I'm probably missing something obvious, but I guess that's my learning curve showing.

If I am understanding you correctly, it makes sense for the coin to be thinner at the periphery where the misalignment causes the bevel on the die that creates the finished rim to miss the coin. The field on the die is higher in relief and would just eradicate the proto-rim altogether or not make it strike up fully. And yes, 1972 was epic for misaligned dies. I have tubes of them.
