2022 D Wilma Mankiller Struck Through Obverse Reverse

You take photos very close. It is OK, I like more hole coin at 50x max. For the fiber: The only possibility it is when they adjust the dies. Why? Because they take the planchet manually, with gloves and arrange in the B-Roll, then is strike progressively to see the convenient and best strike. The gloves are 70% silk and 30% cotton. the fiber is electrostatic material (only the German manufacture of the machine know). So those fiber can go out and glue to the relative wet and greasy planchet and put in B-Roll. So during the tests could be strike trough. Now the question it is why those coins go on the market? Normally are 200 coins, the first ones sure are put manually away, the last ones will go with the normal production.

For me your coin seem to be the last stage of adjustment, I will say is at 75 to 85% of the adjustment proceeds. This it is. I am glad you look at the films and you understand more about modern coins production.

This it is my feeling about your coin. I was involved on those procedures, but I can not disclose everything except for specific coin.

I don't believe it's struck through, but I also don't think it's PMD. I've seen a decent number of similar things on recent quarters, and it seems to me to be some type of planchet defect. Here's a similar coin I posted last year. http://goccf.com/t/407962

@RW and @SAM. If you has those, for me are mean that the Mint was in very rush for production, and they go on without calibrate in the early strikes the dies. Very interesting. It is a really discovery for me. All's we know that they postponed the strike due to different restrictions. Interesting.
