Is this an RPM to the south or something else, e.g. Die Deterioration?

I can only see what might be a distinct RPM south of the mintmark, that does not look like the streaky lines of Die Deterioration, when I angle the slab and in closeups.

Notes
There's no known RPMs on a 1974-D 50C.
This coin has an MS67 grade, so if there is a subtle real undiscovered RPM, this would be a coin that it might show up on.

I'm thinking that it's Die Deterioration Doubling. I can see die flow lines.

Here's a better image of the lines in the area.

There appears to be die file lines covering the area, perhaps to address an RPM? I wonder if in the closeup those might look like flow lines or if there's deterioration too?

Die file lines? Looks more like flow lines from a worn die and that is causing slight Die Deterioration of the mintmark.

that is some extreme close-up image above - makes it look like something it isn't

This looks more like DDD if anything at all.
