2021 D Quarter Need Help With An Error

There was another similar post a few weeks ago. The op said he was going to submit them. I wonder if they ever did? And coop might be right.

If they were from an original roll, they are probably stained metal. If they are from circulation, someone could have altered them. Try checking new rolls of All new coins. That will tell if if this is normal or something special. But in original rolls you still have bad ones in them. It is the better ones to save. The rest, then them do the work they were created for. Making change and working in vending machines. The mint is just into it, to make money. (pun intended)

If these had circulated at all then I think it would most likely just be surface staining.

Thanks Spence. I'm still uncertain about what kind of staining would be created at the mint. There were some that had grease on them but those could be wiped off. These I couldn't remove anything and the ones with grease didn't have the striations

I figured that if for whatever reason the planchets got piled up in the oven trying to meet production or something and the temperature was off with the different variations some light some dark that if I found one from the top that one would be black. I just found this one and I think it's the best one

Those crescent shapes on the coins lead me to believe something like that has occurred. They seem to have the same arch as a quarter.

I found around 11 very similar to these a few months ago in a brand new box of uncirculated coins and posted the photos on the forums. I did send a couple off to be graded. They are currently showing a status of Grading/Quality control. Hopefully I get them back in a few weeks. I will post the results as soon as they are back.
