Miss Italy21 Valued Member United States 163 Posts	Posted 10/09/2021 06:01 am What would cause a new 2021 quarter to do this? Sending pics. I've seen older coins with deterioration and the black marks of oxidation, but a new coin? I know environmental issues can cause this, but on a new coin? It looks like a double cheek on his face? It's very odd? I got this as change the night before and was going thru my coins and just noticed this. Report this Post to the Staff

merclover Bedrock of the Community United States 10635 Posts	Posted 10/09/2021 10:29 am I agree with all of the above. Some sort of environmental staining/toning/damage post mint on yes, even new coins. Who knows where it was to get this way before finding it's way to you, but it didn't leave the mint looking this way. Nothing in the minting process could produce this sort of damage.
