RW now I see. You has rolls from one of the 12 main banks who receive the coins from the Mint. I presume one of the counting machine has a default. Is damage for me to see this ignorance from their contra part.

The Salt River Bay has the exact same phenomenon going on with it. Starts off thin on one side  Then flares out on the other side  With the same gritty grease look on the bust

The last two photos you put from you and your friend, put me questions. The letters are struck over the lines. If is the die polish problem will affect normal the flat surface, and not the relief like the last photo where the high relief is affected and the letters are perfect. The first photo you put the rim was affect. We forgot. The rest ones is the coin relief and surface. Do is the planchet default scratch in rolls before milling? or the lateral band which direction in milling detached a little bit and some blanks was force and push? Big question.
PS: Look slow at the videos, maybe you can find probability there.

Thanks Silviosi. Sounds like you see this is pre strike or a striking error not PSD. I know you know your stuff but we all see new things and learn everyday. That's the beauty of life

Thank you, but remember not the first coin with the rims. And please take the link and watch to see how is work. If is need more links for, with pleasure I will put. Like this maybe the community will analyze the coins by years strike, and not by old kind. We has to adapt.
PS. For me a pre-strike error is not a strike error, is Mint processes error, which old kind of thinking do not exist. Are mean this happened before strike the coin and is related to planchet and blank preparation.

Those look like armor car company (String & Sons?) or something like that, wrapped rolls. Maybe Mike can clear this up? John1

Banks do not wrap their own coins, places like Brinks does. The U.S. Mint uses special paper. John1

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.

the mark is on both sides in the same location. That says damage to me - like something crushed it.

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.
