Hi Mya, I know you mean well but what you have described is a really good way to cause harm to a coin. Leave them as they are for the most part. Expect a lot of responses like this. clembo
Yep. The wiping with paper towels and qtips is probably the worst part. It will leave hair-lines that will destroy the value of your coins. I don't know if the salt would have any adverse effects. Probably.
