Tone Question

I think that these types of rainbow toning are from enviornments where many kinds artificial elements are present.

It's more if they deem it as market acceptable. They have a pretty good eye for toning but I'm sure they've slabbed some coins that were AT as well as others being denied that are NT'ed. Toning is a extremely complex topic, one cannot learn to tell the difference between natural and artificial toning in an instant, it's something that only time and experience looking at hundreds of toned coins can do, and even then there's ones that will slip through. I'd say the TPG'ers are pretty good about knowing the difference but do get fooled on occasion.

I don't really feel like getting in a huge debate, as many people have different views on this topic... And it's late. But most toning, wether in a album/roll for 40 years or put in an envelope on a window sill natural.. Maybe done on purpose to basically ensure/speed the process with the later but still natural. Every metal tones, that's why people have silver/brass polish.. The know there silverware, jewelery, flatware, brass bowls etc are going to tone... Even if there stored in the safest way.. So why are people surprised and mad when there silver coins tone? Your really not expecting this? Lol

I feel that dipping a coin is far more unnatural than toning on a coin. Obviously coins toned with chemicals and/or electricity I would consider unnatural, and don't condone in the least, but otherwise I'd expect my coins to eventually get some toning. At some point, maybe not in our lifetime, but eventually.. Silver coins, no matter how there stored, will tone.. Like it or not.

And beautiful rainbow colors can be obtained just as naturally and in the same process that dark, Unappealing coins do. Those vibrant blues, purples and reds can come out on one coin in an album while the two next to it turn black, it has nothing to do "with a different environment or smoking". Can smoke tone a coin? I'm sure it can. But natural occurring elements in nature/the air can bring these colors out just as easily and for some reason can affect one coin while the one next to it stays white... Or turns dark.. There toned by natural elements in this world, how or when they come out is anybody's guess.
