I'd stake my life that you are wrong Ruben. I should also mention that someone who definitely has a stronger background in chemistry than everyone here combined that I am related to has explored this to the fullest. But I'm not going to argue with someone who doesn't know what they are talking about. Claiming this is related to the laws of thermal dynamics.....
Dear Zane, While I respect your opinion and I'm certain your ernest in your belief on this I don't think you know anyone with a greater background in Chemsitry than I have, although its possible. But if you do, go back and ask them how Intel and Shering Plough do just this on a daily basis. BTW - It is ALL based on thermodynamics (not thermal). Every process requeires a release of Delta H and Delta S for it to proced and it is ALWAYS finger printable. Advanced chemical/pysical problems are broken down to 2 basic kinds, Kinetics and Thermodynamics. This issue is the second one.
Btw, I hope I am not coming off as a jerk. And Ruben, I can absolutely guarantee the person I am referencing has a much stronger background in Chemisty. They have 2 PhD's. One in pharmaceutical chemistry, one is analytical chemistry, and they graduated with a 3.99, and finished all degree work including pharm-d degree and both PhD's in under 6 years.
Ruben, I vehemently disagree (about dipping), and I would like to apologize, as I feel I definitely came off as a jerk.
PharmD's have no chemistry background worth mentioning. The Pharmacuetical Chemistry, is Phys Chem. These companies need to examine diffusion coefficients within their scale ups for highly sensitive electrostatic compounds constantly. They need to examine the alloy compounds of the duct systems and to see that they are cleaned within prescribed specifications and they look for fingerprints from the chemical compounds. And then there is the work of discovery of new coundounds with includes similar therodynamic examinations. In the computing field, this is even more intense and the entire CPU building process is derived from changes based on washes on waffers at include etching lengths,and proper diffusion and compound mixtures which affect changes which would make those alterations from a dip seem like the grand canyon.

I would argue that those with a PhD in analytical chemistry, have quite a strong background in chemistry, which the above mentioned person has.
Analytical Chem is ok but the Pharmacuetical Chemistry that he has, if it is like my program, is where the bread and butter is at. Thats really an advanced application of PhysChem, one of the toughest and most educated PhDs going. It makes most PhDs seem quaint Ruben
Do you think they Dip those Peace Dollars on Coin Vault ? They sure do look like they just minted them.
They most probably dip those coins. Also, in an attempt to moderate the above disagreement before it gets any worse, I do NOT have any degrees in chemistry and am therefore qualified to say: Just agree to disagree and move on. Why argue about something that you will never agree about. This is supposed to be a fun hobby, not a discussion about the Presidential election, which I totally disagred with my wife about.
All very interesting. However, everyone should remember that if you require something in the order of an electron microscope to detect cleaning or dipping, I doubt that it would effect the value at a standard coin show or shop. I've probably been to thousands of coin shows in my life and the lighting alone makes it difficult to detect cleaning or dipping. Also, the vast and I mean vast amount of collectors really don't know or care about dipping or cleaning. Oh so many times I've heard people say, wow, isn't that a really shiny coin.
I don't think it would take that much magnification, just a learned and experienced view. Dipping removes something from the coin (which is the point, right). That is something that can be measured. Ruben
