PS bright and shiny is absolutely not a grading point. Eye appeal is, and actual mint luster/shine on the coin
But brightness itself is not what they are looking at. Easy to think it is, thats why people have buffed dull coins with a fine wire brush to make them shiny and sell better
You should study this very carefully http://www.ngccoin.com/pdf/nograde.pdf

RareSov: Great link you provided. That answered a lot of my questions. I also located the "Altered Surfaces" thread (pointed out by 'itsnowtoo' and found that to also be of real value. I appreciate all the help everyone provided.

Get a second and third opinion on your coins.Believe it or not,serious collectors do know the difference between "original and "dipped" surfaces. Original Uncirculated or near uncirculated and toned coins do bring a premium from the right buyer.Also,rare circulated coins as well.There are people who will dip a coin with "ugly toning" and sometimes it pays off but not often.I sure would like to see some of what you have.

You should not remove or move metal . Dipping in pure old tarnish remover may be removing metal . Part of the value of a coin is the fact of the condition . It is very tempting to slice off that upturned metal or burnish away a shallow scratch , BUT DO NOT DO IT . That may be considered Altering or even Counterfeiting of Condition and will most likely be detected anyway . There are penalties for some of these things . That said I admit I clean coins . I hate dirt , grease , oil and whatnot on my coins . Germs gotta go away . If I choose to clean and I do not always , I use soft hand soap and either a Camel Hair Brush or a Soft Cosmetic Applicator Brush and very gently ease the dirt off of the coin . Weak Isopropyl Alcohol was called to use once and also Strong dish soap . Always rinse well after this if you do it and dry very carefully as even a soft cloth may change the appearance . I probably clean 30 % of the ugly coins I get and the rest just stay ugly . Serious coin dirt I cannot stand and if there is an AU55 in there or even an MS Grade I find it hard not to clean . Whizzing , serious dipping , rubbing and all such is for amateurs and those that wish to deceive . I am returning a 1901 Morgan this week that wash rub polished . The weak picture fooled me .
Hope this all helps , if I am way off hit me with scorn here and now .

This is not a post for or against cleaning, but in actuality, the services tend to grade the bright and shiny coins MUCH higher than the same coin with light toning or haze. The brightness of the luster is a major grading factor because it can overpower even the most prominent field marks, sometimes allowing a rather baggy coin to grade gem. The same baggy coin with soft golden toning or a little haze might grade MS63-4, in many cases.

Cleaning is misleading, to remove dirt from a coin but not altering the original surface is okay (conservation). To change the surface of the coin by removing the outer skin via "dipping" or making a natually toned coin shiny is what everyone thinks of as cleaning and the purist don't like that.

Hi all,
Since this thread is back in action, here is the coin I referred to above
There is still a tiny bit of peripheral toning. Before, this toning was not clear because originally the whole coin was slightly hazed. The seller used light dipping but some remained, so I sent it to NCS
