Do you Consider a Dipped Coin to Be Cleaned?

I have submitted coins that i personally have dipped, they came back with straight grades.

 

A brave admission in this environment!

 

So when they put "Details Corroded" on a label they are telling the truth but when a coin is toned and they don't add "Details Corroded", then they are lying?

 

At some point corrosion moves to where the coin is considered damaged. There are also different kinds of corrosion. Toning is oxidation and if a coin oxidizes too much they will details it.

It’s just like coins that have been scrubbed. Sometimes a little bit of hair lining will pass because they decide the coin isn’t a problem. Severity is the key.

 

Ask NGC if "Conserving" the Norweb coin was a good idea. Like I said before, dipping is erosion, plan and simple. If you put it back into the same environment, you have done nothing but hasten its demise. If it has been exposed to natural atmospheric conditions for it's entire life, it will survive on it's own and be much better for it. If it has been exposed to a very harsh environment, eroding the surface off isn't saving it, where removing it from that environment would be.

 

Bingo. Winner winner chicken dinner. But alas no because the TPG Firms MUST keep up the mith that their cleaning service isn’t cleaning but conserving so they aren’t lying. Wink wink. Just chemically altering the surface of the coin by stripping the toned no, tarnished no, oxidized surface OFF OF THE COIN! Sounds like double talk to me.

You are right. After dipping a coin the fresh surface is more reactive than the coin was before. So proper storage is key or long term you are worse off based on what I have read.

You’re wrong. But I don’t know how to help you understand. That’s ok. You can be wrong.

Thank you very much, Jim, and a belated thanks to @GDJMSP as well.

I also hope they're of assistance to some involved in this discussion.

 

First air conditioner was made in 1902. So before that, it was almost impossible to properly store coins. Of course, just because it was invented in 1902, doesn't mean it was widely used. I grew up in a home built in the early 1960's and it didn't have air conditioning until we had it installed in the early '70's.

So without wide spread use of conditioned air, it was nearly impossible to properly store coins.

I've read your posts in this thread and I agree with them. This post is meant to provide supporting data to your improper storage comments. Without the ability to remove moisture from the air, toning/corrosion would be difficult to prevent on coins.

 

Put them in a glass jar, put a cork in it, seal it with wax. The mass of air and humidity trapped in the bottle is tiny compared to the mass of the coins. Once anything reactive in the bottle combines with the coins, reactions stop.

 

Jeff, you have the beginning of a folk song in the first sentence

 

"Put 'em in a glass jar...
Put a cork in it,
Seal it with wax..."

 

I have noticed a lot of darker toned earlier circulated coins ie bust and early seated that come out of New England. And I mean from old estates not collections you get a lot of the almost black circulated cameo ones a lot of times and I always attributed it to the massive amount of wood and coal smoke in the winters the last 209 years and all the sulfur compounds in it just like antique weathervanes from eastern Massachusetts and any of the mill towns in Maine and New Hampshire will have a very heavy dark green copper verdigris patina compared to ones from more rural New England and upstate New York (I deal in antiques and specialize in Americana and folk art) and have had dozens of early weathervanes and have examined hundreds if not thousands

 

That's the type of experience that can give you the ability to determine authenticity with high certainty.

 

Cyanide , the dip of antiquity!

 

So how do you protect the temperature of the jar with no air conditioning? The jar would get warm, wouldn't condensation form on the inside of the jar?

 

Sure, if you put them in damp or when the air was humid. But if you put them in dry, especially if you put them in during the winter when the air is cold and dry, there won't be enough moisture in the container to form condensation.
