What are the water looking spots I see on pennies, can they be removed and with what, or does it matter or affect grade? I've hear acetone a few times but I am reluctant to do anything too a few that I think might grade at 65 or higher.
They are a nuisance, annoying and occasionally heartbreaking. Nothing irks me more then to see a pristine, glaring cherry red, spotless reverse only to flip it over and bam...SPOTS! grrr. Rant over.
Just a normal part of the mint process. The spots are permanent....unfortunately. That's the whole trick to getting these in higher grades, no spots. It seems like when I find one that's very clean, it will have some nasty hits on it. LOL
