And not to start a new topic but maybe question in which you were trying to infer would be, "Which school did you attend". I could have been vague in my answer to, "where did you go to school"? and said America.
I'm not so sure. Note I quote "cleaned" There is only one word currently to describe the process. I would rather call it preserving but I think there is trouble distinguishing the two. What If I posted my proof quarter here, sent it to grade, broke it open "cleaned" it, and then see what happens when I send it back. ???
Not a danged thing wrong with working with your hands. When I got out of school I wound up driving a truck for thirty years. I loved working out in the elements. Now, back to subject. When I was a lad, my father showed me an 'Oregon Trail' commemorative that he had cleaned with Tarn-x. Yes it was bright and shinny, and at the time I admired it, with its' mercury like appearance. But at that time I lacked the knowledge or experience to appreciate the original 'skin' of the coin. Anything original about the coin had been wiped out. It was nothing but a brilliant disk exhibiting no character at all. It lacked life and luster, but to a youngster, it was appealing. would you ever consider 'cleaning' something like this? Don't mess with original skin........
This is undesirable toning to me. If it could be cleaned, w/o leaving dull, washed out surfaces, I'd say go for it. Conserve that sucker.
