A real sleeper in this category, I'm lucky enough to have or have access to all forms of the packaging, and lots of them. The base was mostly wax, vending and grocery racks, with very few from regular racks and cello Packs. Racks seem to be less available than prior years, and cello as well. The grocery racks are, for the most part, abhorrent quality, with substantial print/ink issues on top of our topic, centering.
I collect and sell high grade commons from 72-86 FB, and it is correct that 1979s are a nightmare. There is even some disagreement about which bottom centering variation is perfect and which is 55/45.
But I think if 1980 collectors were compelled to send in enough cards to meet the numbers of other sets, 1980 is the centering nightmare. I am attaching the Bob Griese photo, these are 40 percent grocery, 20 percent wax and 40 percent vending. Note that these are not all collected in those cases, many were 'miscut' where the (usually) left border was involved with the

The NM+ to NM-MT example is from my local star dealer who has about half the number I have but I understand hhis to be 80 percent wax and about and even split between vending and racks.
The Griese card is on the second or third tier of the most difficult to find centered lists. See Mark Washington, Sherman White, Hasselback, etc. The set isn't flashy and doesn't have a Campbell/Montana level Rookie but I think it warrants more buzz due to these centering issues.
