Kennedy Half - What caused this mark?

It has the appearance of a fingerprint, but I have seen the identical mark (in the exact same spot) on several different coins from each of the top-3 TPG's
Would this be considered a Variation?

I have collected Kennedy halves for a long time and have not seen that before....Perhaps I missed it. Is it the same year coin each time? If so, what year? Cheers, RickO
Looks like a finger print.

Yes the year, mint mark, pattern and location are all the same.
Here are some examples:
Based on those pictures, it looks as if the die had rough polish lines that were not buffed out....Interesting find.... Cheers, RickO
They all appear to be from the same batch/run.
Is there any other noticeably similar characteristics? Die scratches or something elsewhere?
I'm also thinking it was the same batch (or die) used for all of these. I have a few of them and the pattern is strong on some and "lighter" on others (as if the pattern starts to fade near the end of the print run for that die). I did look for other identifiers, and nothing else stands out as appearing on all of the examples.
Wow, I want one! My first guess now is a struck thru that squished out on one die. Less likely is a finger had a chemical on it that etched one die.
Whatever it is, it is an anomaly in the die. It happens all the time. If it is exciting and distinctive enough people might consider it to be a variety.
What is the date of the coin or are you going to corner the market? LOL.
Anyway, what were the coins from each service graded? They CANNOT be 70's!.
A new worker was on his first day on the job. His task was to fingerprint new coins. In this case, he failed to follow guidelines, and put his thumb smear in the same spot on the entire day's output. Later that week, he was transferred to the department where nails are inserted into coin presses in place of planchets.
Oh my...
For a minute I thought I was on one of the other forums I rarely frequent anymore.
