The PNG, acceptable and unacceptable practices, coin doctoring, etc.

One thing I think should be added to the language of this paragraph would be to include the use of any oil or oils on coins, specifically including the products Coin Care and Blue Ribbon.

Was there any discussion on that particular point ? And if so, what did that discussion entail ?

I think you're going to have a problem with this paragraph, particularly with the parts I underlined. This will preclude the use of coin dips on copper. Not that I think they should be allowed. But there's no getting around the fact that it happens. Nor is there any getting around the fact that when a coin, even a copper coin, is properly dipped, there is no way to prove that it was dipped.

So saying that you are not allowed to do it serves little practical purpose since you cannot prove that anybody did indeed do it. Except by using deductive reasoning. And deductive reasoning is not proof.

In the first sentence, do the underlined and bold parts of that sentence include intentionally placing coins in old albums for the purpose of toning them ? You can also include tab holders, paper envelopes, tissue paper, many after market plastic display holders, and a plethora of other possibilities.

With most of those things, but in particular those that I have underlined, proving that any of those things have actually happened is impossible.

I'm not saying this is easy, it is arguably the single toughest hurdle there is to face. For how can you prove intent ? And intent is the only difference there is between the guy who intentionally purchases an old album and then puts coins into it to cause them to tone and thus increase the eye appeal and grade, and the guy who has merely used those old albums all of his life because he likes them.

And since those old albums, the paper envelopes, the tab holders, the tissue paper etc. all put off the very same gasses that cause the toning. There is no way to differentiate between them and the guy who injects those gasses into a sealed container to cause the coins to tone.

And again, the dipping issue arises. For it would be hard to argue that dipping many coins does not increase the eye appeal and their grade. The comments in this paragraph are in direct contradiction with later paragraphs.

 

You sure about that ? Were you aware that NGC and PCGS both have been known to dip coins while those coin were in their possession - without notifying the owner or asking the owner's permission to dip their coins ?
