Featured Can you define artificial toning ?

Agree with this, as far as I have seen personally.

I believe they were, but we’ll never know. That was about 15 years ago and the only one I KNOW I still have is a 1961 proof dime that WAS brick red and purple for years, but has now turned anthracite. Colors only still pop under very bright light and overexposure. The attractive colors are temporary. But in this “hit it and quit it” world, who cares, right?

I put that dime in a single dime Capital Plastics holder.

 

I have also toned silver with my Kodak “dip” when the pH has been turned slightly alkali with baking soda added to it. Turns out thiourea can either add or subtract toning depending on the pH.

 

So you are saying that coins that are AT by the application of chemicals to the surface will “turn” over a period of years.

I have owned hundreds, maybe thousands of TPG graded rainbow toned coins in my life, and not one has ever turned in the holder. Now I’m not saying that there has never been a coin turn in its holder, but I am saying that direct application of a liquid solution is not the preferred method of coin doctors.

 

Quick little experiment this morning:

 

And I am TELLING YOU that not only has EACH AND EVERY slabbed coin I own with ANY TONING AT ALL HAS TURNED, many UNTONED coins have become toned in TPG plastic. I don’t send my experiments in for slabbing. I have ethics. I have never seen a stable toned coin in my life. All they do is progress. It is a certainty.

And you’re right. Liquids are NOT preferred. Gases are.

 

Kurt, that statement is ridiculous.

 

Prove it. Hahaha.

 

What does "anthracite" mean?

 

Coal

 

Thoughts on my little experiment above?

 

Looks like you ruined a coin somehow.

 

Have you ever had a non-derogatory thought? Asking for a friend.

 

I’m not tasting the rainbow!

 

Huh?

 

It was a very rugged setup. It needs work

 

The point is to use heat/chemicals to accelerate the formation of rainbow toning that will both drive a premium price and be market acceptable in the eyes of the TPGs.

Your experiment just looks like you put that coin in the oven for a while. I also think you were being a little tough on Coin Corgi. My initial reaction was “that poor Kennedy just got ruined” I kept it to myself in an effort to be nice, but I really think he was just being honest.

 

First time I've ever agreed with you I think! lol

 

Hey, Thanksgiving is next week. Snag up some silver, some clad, and go nuts with the side dishes, right? Heck, throw a Morgan in the bird cavity. You feelin’ me? It’s all for the glory of science. Heck, if the Brits can bake a 6d into the plum pudding, why the heck not? Who’s with me?

 

Almost blackish but with shimmering color still showing through. Just like a hunk of anthracite coal. In fact, in anthracite coal, the color comes from the same optics as rainbow Morgans - dichroism.
