<p>[QUOTE=&quot;GDJMSP, post: 1665142, member: 112&quot;]First of all, dipping coins (properly) has been perfectly acceptable by the numismatic community (and yes that includes the TPGs and CAC) for as long as dipping coins has been around. That has never changed, and I don&#039;t see any way it ever can change.</p><p><br /></p><p>That said, pretty much anybody who knows coins will agree that 80% or more of all older coins have been dipped at one time or another. Toning is inevitable, that is just a fact that must be accepted. What I said in my other post about storage methods applies to all coins.</p><p><br /></p><p>As for what you ask about paper rolls, yes it is possible. But, paper rolls did not even exist until around 1900. And paper rolls were not commonly used, by banks or anybody else, until around the 1930&#039;s. So you have to take the age of the coin into consideration if you want to use that possibility as an explanation for the coin not being toned. And even then, most coins that are stored in paper rolls do tone, the paper itself encourages the toning. Those coins stored in paper rolls that do not tone are the exception and not the rule.</p><p><br /></p><p>The point is, yes there are some examples of coins, and I mean all coins not just copper, that managed to avoid toning over the course of their lives for one reason or another. Usually it was nothing more than pure accident, because as I said earlier, storage methods that helped to prevent toning did not exist until recent years. A coin here and there might have been put into an old fashioned tin with a tight fitting lid, or a glass jar, and that may have kept those coins from toning. But how many examples like that does anybody really think could exist ? Sure there are a few, but very few. And definitely not enough to account for all of the untoned examples of older coins that exist today, and especially not copper.</p><p><br /></p><p>So the only logical conclusion is that those untoned coins had to have been dipped. There simply is no other explanation.</p><p><br /></p><p>However, many believe that copper cannot be successfully dipped. This is because dipping copper causes it to turn a pinkish color, an unnatural color. And that is true. But it is only true if you follow standard dipping practices. If you dilute the dip correctly then copper can be dipped successfully.[/QUOTE]</p><p><br /></p>
