A thread on E1/E2 got me looking at my collection of these BOB items. I was quickly drawn to the E6 variety when I saw the note that there was a variety with "Damaged Transfer below the N of CENTS". Here is what I found.

Now, what I would consider the normal version, and the closeup of the area of interest:


Then, a version where there appears to be a slight bit of damage to the area of interest:


Next, something is definitely happening here:


And, finally, a full-blown, damaged version:


I believe the last two would qualify as damaged versions. It is interesting to see third version where the transfer is "almost" damaged, but not quite.
