I recently acquired a box of brand new 2020 Marsh-Billings- Rockefeller and pulled these W's out. I don't believe these quarters were ever in circulation for commerce. I believe they went from the mint and went directly or indirectly to the coin rolling company's and then to the banks.

I've noticed this distinctive and similar stain on many (most) of them. I've used acetone on them and it didn't budge!! It looks like it's baked into the surface. I'm thinking maybe it was some type of oil or chemical that originated at the "West Point Mint" and/or used during the minting process. I don't think it's coming off but I'm open to suggestions.

I've looked at thousands of brand new 2020-P's and have not seen this stain. It only appears to be on the W's.

Have any of you guys seen this anomaly on your 2020-W coins? Do you think a TPG'ers conservation would or could remove it?

I'm lazy and go the the local coin shop and buy the America the Beautiful Quarters. They have them in mint rolls. As I pick through the rolls to get the best examples I have noticed A LOT of coins coming straight from the mint with these stains. That's why I search them and find examples without them. I always assumed they were a residue from some sort of rinsing process that isn't fully removed. I virtually never saw this on S mint coins. The worst was Philadelphia. I'm surprised West Point coins have this residue on them.

That's a real bummer to find them in the roll like that. I would have thought West Point would have better quality control than that since they aren't producing billions an billions of coins per year.

I've always assumed it was some sort of mineral deposit. Kinda like spots on your car after it was washed and rinsed with hard water. These are all assumptions on my part so anyone feel free to correct me. If they are soapy/hard water spots, acetone will not remove them. They will most likely be made primarily of calcium carbonate. In the industry I work, calcium deposits are removed by acids and are not affected by solvents. Of course, you wouldn't want to put harsh acid on them, but I'm wandering if you may be able to experiment with vinegar (acetic acid) on a coin you care nothing about with similar spots to see what kind of results can be obtained.

Anyway, I know vinegar is a big no no, but maybe a quick dip and thorough rinse will remove the stain.

Just my thoughts. Good luck!

jpbone-

Thanks for the reality check. Your explanation of some type of dried residue from a rinsing process sounds very plausible. That's pretty much what it looks like.

I might try diluting a little vinegar. Thanks very much!

Yuck.

A good reason to wish they had offered these as a direct sale from Mint. At least the chance for better quality exists.

I pulled 11 out of a box last week, I think only one had a spot on it. The issue I noticed on mine was a small nic on the rim that affected one of the reeds, about half of them had it.

Link for pics. http://goccf.com/t/384905
No close ups of the rim though.

Ty- Thanks for that link!

Unless I hear from others, I'm wondering if mine are an anomaly. And where the heck did these stains come from? : (


BTW jpbone, no joy with the vinegar.

There was an article, on the spots on ASE, and it was soap not rinsed completely after the cleaning process. Webekin
