1964-D 25c - Odd Mintmark 0

I'm not sure what to make of this one. It looks like a Small D over Medium/Large D. The prominent "small D" is shattered in three places, with two chunks hanging off of it. There are several "D/D North" RPMs on Wexler's and Coneca but I haven't matched mine to any so far. There is a WRPM-006 on Wexler's with a similar appearance, but the D/D is rotated and south. Small, Medium, and Huge D are shown in Cherrypickers under 1952-D for comparison with the 1952-D Huge D variety, but no context as far as where the other MM sizes were used. Overall the reverse seems like a normal AU to me. Thoughts?

Here is the Wexler's WRPM-006 for comparison. The arrow seems to be indicating notching of the D/D, but zooming in to me it looks like cracking of the upper left similar to mine but not as severe.

Interesting MM. Nice photos, too!

It's an example of repeating strike doubling from the die having been slightly deformed at the mintmark.
