Apparently you were not joking when you said that before. fret - using soap, of any kind, on coins is one of the worst things you can do to a coin.
I do not have enough time, nor is there enough space to list all of the different kinds of problem coins.
Ouch Fret , hope you at least soaked them good in distilled water . I put a '64 Kennedy in distilled water and some dishwashing soap and the coin turned a light purple , some of those dish soaps have all sorts of weird chemicals added .
Just ask Madge......... [video=youtube;dzmTtusvjR4]http://www.youtube.com/watch?v=dzmTtusvjR4[/video]
When you crack open a slab then wash the coins with soap, should that coin be returned to the slab? Shouldn't have to be re-graded since it is improperly cleaned. I have thrown a bunch of pennies I was saving for their copper into the sink and washed them but these are not worth anything.
Environmental damage - this covers a broad spectrum of individual things that can happen to a coin. Think of it as a catch-all phrase. Harsh cleaning - again a broad spectrum. Artificial toning - self explanatory. An altered coin - such as added or removed mint marks. Tooling - re-engraving details on the coin to make the coin appear to be better than it is. Over-dipping - a coin that has dipped to the point that it becomes washed out. Both MS and circ coins can be over-dipped. Damage - again a broad spectrum than covers anything from rim dings to scratches to gouges to being bent to basically anything that damages the surface. Polishing - self explanatory. Jewelry mount - self explanatory. As I said, I can go on, and on, and on.
