Interesting doubling on reverse of 1968D

Below are photos of the back of a 1968D LMC.  They don't match any existing DDR varieties and my suspicion is that they are simply die scratches / gouges, but I figured I would get a second opinion.  Though not photographed, I ran across another 1968D that had similar, though weaker vertical lines inside the right-most column as well.

Note the apparent doubling inside the right
most column.

Though difficult to see, there is raised area akin to
a rotated punch of the vertical bar in the 'F'

1960D RPM

Definitely a 1960D RPM (my first) but which variety?

Closest matching appears to be [1960D-1MM-027] but the die scratch marker for the 'Y' doesn't line up w/ the marker for 027.  There is what looks to be a die break beginning on the cornice and what looks to be a small tail showing on the 'U' in 'PLURIBUS'.  The differences in the later two could be explained in that my coin is EDS and the reference @ CC is MDS, but die state wouldn't explain the misalignment with the 'Y' marker.

Note the NE running die scratch from the inside of the Y.
In 027, the scratch begins from the outside of the Y.

Potentially the beginnings of a die break on cornice.

Perhaps a baby tail running SE out of 'U'

Potential RPMM Finds

Note the splits in serifs at the points indicated.  I'm not sure which variety these are as they are pretty beat up so most of the traditional markers aren't visible.

UNDERSTANDING AU58

The coin below is an PCGS graded AU-58 1972 DDO LMC.

Compare this to this 1974D that I found in a customer roll I purchased from a bank.

If the highest grade available to circulated coins is AU-58, I think that means that the 1974D I found at the bank will be graded the same (AU-58) as the 1972 LMC in the first photo.  If you compare the clarity and details of these two coins, the 1974D is of a significantly higher quality. This begs the question, is the 1972 over-graded or does the AU-58 grade have that large of a quality range.

UPDATE - so based on my friends over at coin community forums:

1. The 1972 is potentially overgraded - more along the lines of an AU-55.

2. Just because a coin is found in a blended roll @ a bank does not automatically disqualify it as Mint State (MS) quality.  The initial guess was that the 1974D above is actually around MS-62 in grade.

1970S DDO [IN GOD]

1969S DDO

UPDATE - This is a clear case of machine doubling (MD) or strike doubling.  Notice how the double takes away from the details, is shelf like, all in the same direction, and both the date and mint mark show the effect.  These are all clear signs of MD.
