[QUOTE="bhp3rd, post: 754040, member: 16510"][b]I agree with Dutch on this one, it's very common knowledge[/b] I agree with Dutch on this one, it's common knowledge with more seasoned dealers and some collectors. I have mentioned this before (and was kind of jump on then) and no, I do not have facts other than experience to back it up but think for a moment. Plus the issue, for my input in this thread sake is concerning high AU to MS, mostly Morgans, Peace and higher end Barbers, Seated, Walkers, dollars, halves, and quarters. Silver tarnishes quickly - just the increase from .900 to .925 has a dramatic effect. .925 tarnishes twice as fast as .900, so we know it does turn fast. A [B]properly done dip on a nice mint state coin[/B] does not hurt the surfaces at all. Cleaning of coins was for many decades the preferred, acceptable normal treatment, everyone did it and expected it done. It is not logical (if you really think about it) to think that big silver coins from 75 to 125 years old would remain so blast white today. Just put proof silver state quarters in a Dansco album and then look at them again in six months time. There was no air conditioning during the first 35 to 100 (or more) years of these coins existance, nor was there practicably any thought to air tight or humid free evvironments. These coins (the dollars) were kept in sulfer laden cloth bags in humid dark often damp vaults for decades. While many are in denial, with the issues mentioned above how is it we have 10's of thousands blast white coins today - it's just don't add up or is it logical that the common (or uncommon) MS-64 White Morgan you have in your hand was not at some point cleaned in some way at some time.[/QUOTE]
