I found another dime with the same error/damage. Can you look at these dimes and tell me what you think about them?
Thank you in advance for your opinions

Re: 2019 Roosevelt Dimes
Sorry but there is nothing in the minting process that would do this to a coin.

Re: 2019 Roosevelt Dimes
Someone took a sand paper drill and applied it to the coin - that's what it looks like :)

Re: 2019 Roosevelt Dimes
I had to Google "pmd". It's hard to understand technical abbreviations in a new field of endeavor. "Post mint damage", hmm.
That is an odd chemical or abrasive occurrence. I had not seen this before in circulating change.
You'd think a minted coin would be quite durable as they are meant to last for many years and perhaps hundreds of thousands of transactions. So what could cause that kind of trauma to a dime.

Re: 2019 Roosevelt Dimes
I got to the factory and ran two quick tests with our staff.
I took a dime, and fine sand paper, and made 100 unilateral passes. The dremel was not quickly accessible.
Noticing the distress and rim flattening, we also ran over it with our forklift, then a steel cart.
That's about all the time we had to spare for this interesting experiment.
In this first set of images the dime before resting on the rubber pad, the 100 sandpaper rubs. And showing the metal removed on the now discolored sandpaper.
Does not really match the original submitted and damaged dimes. But it does indicate a unidirectional damage. The rim is reduced and the face high points are damaged. My images clearly show scratches, but no dark splotches.

Re: 2019 Roosevelt Dimes
In these two images, both the same just different light angles. The rubber tires and the steel wheels only left a few scratches.

Re: 2019 Roosevelt Dimes
It seems like you are having fun experimenting .
The problem with trying to identify EXACTLY what made the damage to the coins is that there are as many ways to damage a coin as there are tools/people/creative minds.
But PMD is not hard for someone who knows how coins are made to determine. Its simple matter of understanding the minting process and seeing what might happen due to the systems used. That familiarity and knowledge, over time and experience, makes it so people who have been at this all their lives can tell a real error from damage almost at a quick glance.
Think of it this way...when you find a threaded needle, you would never expect someone had tied a piece of thread to their trailer hitch and drove their pickup truck through the eye of a needle and left it there for you to find.
Here are some fun videos about how coins are made and they show the machinery/process etc.
How Coins & Errors are made:
How Coins (and errors) Are Made
Take the (short) time to view these for a better idea of why the people who have experience are calling your dimes damaged.
And if you want to know what types of legitimate damage are done in the minting process, go to error-ref.com and start looking round. The hobby has a person they look up to named Mike Diamond. This website is his, and he uses it to explain all the weird types of things known to actually have come from the mint.
BTW - the flattened details on the REV and the rims also seem to indicate they were hit with something.
