I noticed tonight the seller that has been discussed in this thread, has listed some more Morgans. Now AT has been removed from the headline of the item for sale. However, AT is mentioned in the item description now with an asterisk. At the bottom of the page it explains that AT means artificial toning.

A lot of Morgan dollars sat in canvas bags for many years. When one side of the coin touched the canvas it often became beautifully toned. Are these coins artificially toned as well? If I took a bunch of Morgans and toned them the same way would I be artificially toning them? What is the difference between what this guy is doing and what the canvas bag is doing? |

I'd venture to guess that the canvas-bag-produced toning took months to develop, and the coloration acquired will vary in intensity across the coin, is sometimes non-existent in some spots. AT is instant, and can be made, uniformly on the entire coin, in a matter of minutes.

Peter, in effect, no difference, hence my point. The exact same end result due to the sulphur and other chemicals in the canvas.

that is just proof that PT Barnum was correct.
Artificially/purposefully toned coins are for a different market. We've come full circle: Purposefully Toned Barnum |

My point being that these coins are no different in my mind than a lab grown emerald or diamond. That emerald has the exact same chemical composition as one from the ground, Be3Al2(SiO3)6. It is still beryllium aluminum cyclosilicate. It is no less an emerald than one mined from the ground. Those coins exhibit toning that happens all on its own, just in this case they were lab toned I can even see the argument that a created emerald is superior, because crystals are grown under controlled conditions. In the wild, the stone is beryllium aluminum cyclosilicate + whatever crud slipped into the mixture while it was being made. |

AT is instant, and can be made, uniformly on the entire coin, in a matter of minutes. Since we have no way of telling what happened to a coin after it left the die, we grade based on evidence of circulation. No evidence, it's MS. With toning, we need an agreed definition that doesn't require knowing the coin's history, just what can be observed today. If a Morgan tones from decades in contact with a canvas bag, that's NT. If I get the same appearance by putting a similar coin in the same bag, store it in a 110°F room with a few ppm of sulfur in the air, the difference is how long it took, but you can't determine that by looking at the coin. Then there's a similar coin painted and heated. Obviously AT if you know it was done, but can you tell that solely by examining the coin? |
