2022 D Wilma Mankiller Struck Through Obverse Reverse

@John: the same roll paper was use by the 12 Banks and the security transport company.

As soon as the last strike occurs on a coin, anything after that is defined as PMD even if it happens at the mint, and even in original mint packaging with a number of gouges or other forms of damage on it. While the struck coin is making its way through riddlers, the counting machine, or other processes at the mint, it could be gouged, scraped, stamped by automated machinery (many robots are now used in the mints), or could be scraped or otherwise mutilated. Any of these things, if they occur after the last strike of the dies to the coin, are considered PMD.

A mint error on the other hand is defined as a coin made incorrectly at the mint and encompasses anything that happens to the coin up until the final strike of the dies. The difference is found in if the defect on the coin occurred before the final strike of the dies or after. This is a critical thing to determine in order to know if a coin is a mint error or simply PMD and prove the defect on a coin to be pre-strike (and so a mint error) or post-strike damage.

Thanks everyone for your responses. There are several things here pointing to either PSD or an error. In the end one has to outweigh the other or be a deciding factor to be definitive of what these are. The fact that there is no obvious damage to the devices on several similar coins should weigh heavily. Just my opinion. I could easily be wrong. I will add that a broom in constant contact with a conveyor belt is going to have some fibers pulled out and continue down the production line maybe even into the striking chamber

@RW: Can you take the two sides photo with less glare? Fiber like fiber, but I will like to see better. Maybe change the light? The fiber result in only one situation on those days. I wait for the new photos of the last coin to elaborate. If is what I think, you has for your pocket.

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.
