Ytee64 New Member United States 18 Posts	Posted 03/16/2021 3:49 pm Hi, I was wondering if you folks could tell me what kind of minting error this is, if any and are these type of errors valuable or collectable...as always thank you. If you are interested I can try to give better pictures or one's from my USB microscope, but I can only give a screenshot and that isn't allowed, so... Ytee64 Report this Post to the Staff

Ytee64 New Member United States 18 Posts	Posted 03/16/2021 3:54 pm Hi again, I also wanted to mention that it looks like a "D" over "P" mint mark, if that is possible. YTee64 Report this Post to the Staff

Greasy Fingers Pillar of the Community United States 7059 Posts	Posted 03/16/2021 5:00 pm I've done an experiment with all denominations by leaving them in a pool pump skimmer basket....after a few days the quarter turns up looking like your coin. Report this Post to the Staff

I wonder what is in the pool water that would eat up a coin like that. A swimming pool water is usually PH neutral, neither acidic nor alkaline. Is your pool a salt or chlorine pool?

Dearborn Moderator United States 97227 Posts	Posted 03/16/2021 10:17 pm Quote: Phosphoric Acid 85% ya that's out of the plastic bottle 85% acid, 15% other stuff (water etc) diluted in 35 thousand gallons of more water to achieve a neutral PH of 7.2 I usually use muriatic acid, but still the same. I'm sure it ain't good for a metal object in a pool. I guess that even water is corrosive.. The stainless steel screws holding the main drain cover is still in good order as well as the metal ring holding in the Pool light. (My pool was planted in the ground back in the 1970's....)

They use food grade phosphoric acid to dissolve the dry caffeine and then use that liquid in turn as an ingredient in the syrup.
