Cleaning Experiment.

The other day..I did an experiment..ok, I'll admit it, it wasn't really an experiment 
I took out my silver morgan dollar pocket piece, I'd say its condition is VF. It got dirty from me usiing it and carry it around so much. So I decided a little soap and water couldn't hurt! Well, it did! I was surprised.
Lesson learned, even light cleaning can adversely make the coin appear cleaned, even in soap and water.
The reflective surfaces look normal under a direct light source..but when you lie the coin down and look at it from an angle, the cartwheel does not rotate and it obviously looks artificial.
I also am doing a few toning experiments. I put my MS-68 morgan on a piece of cardboard, let it sit there. It has now delevloped an ugly brown-dark yellow tarnish(toning).
I also put my SMPL MS 67 morgan in a postage envolope (The big brown ones), and it too, has developed undesireable toning, while still keeping its reflectiveness.
I'm amazed at how hard it is to get a coin to tone different hues.
Of course, I'm using the same paper each time. Perhaps if I used notebook paper, that is white, it would cause a different (perhaps more disirable) coloration due to the different chemicals in the paper?
Different paper contains different chemicals, and different chemicals produce different hues of color.
I DO have 2 nicely toned quarters (silver too!) from a nice person on this forum that sent them to me. One is an awesome 1958 rainbow hue, while the other is 1963 dark hue (purple, black, darker hues).
