Check out this site for some good info. Like said, it all depends. IMHO, toning is natural when it is done over a period of time, like say a few weeks, or months. That you can on average detect IMHO. Where if it was accidental, or not, that's a bit more tough, if not impossible to tell in most cases. Phoenix
LOL, He's young Hobo, kids these days huh? Mp3's, high-speed internet, fast food, my-space, microwave popcorn, 3 month toning, it's all good
I believe intent is probably a necessary but not sufficient definition of AT. When someone puts a coin in a cigar box or old album, to me that is natural toning. It's just a matter of choosing a location for the coins that is most likely to impart the toning. I think of AT as someone applying a chemical or heat or something else to a coin that would not be expected to occur in the normal course of storing coins with the sole intent of toning the coins. But I can understand how there is an enormous grey area between NT and AT. I have a few morgans currently undergoing NT in a couple of cigar boxes and a match box. It's all just normal storage. Trust me. :whistle:
LOL. BTW, it wasn't rainbow Morgan toning, I'll try to find the thread where I posted pics. Just was experimenting, and all nat-u-ral IMHO. But I'm not saying you can get all NT toning in a few weeks, lol, but with some coins it can be achieved. Phoenix
I did a little searching on eBay for "Monster" in the coins area tonight and below are two that I found. All of this is Artificial Toning. 1967 Mint Set with a true MONSTER RAINBOW TONED HALF!! Notice how the toning looks like it was painted on. It goes from the field up and over the letters, numerals and Kennedy's hair. Natural toning would usually be a different color on these higher elements. I love the seller's hype about the toning: Notice how he does not say that this coin has natural toning. He simply says if you like natural toning you will like this coin. 1896 P Morgan$ NGC MS-64 VAM-22 Dbl Ear Monster Rainbow This coin looks ridiculous. Again the colors look like they were painted on with a color going from the field and across the higher elements. The toning even goes up onto the rim as the same color. The color sequence appears to be out of order. The cobalt blue looks very unnatural. And what's with the untoned wedge? I'm guessing the coin doctor thought a sucker somewhere would like "dramatic" effect. Take a close look at this untoned area. It looks to me that the luster is impaired. But the coin is in an NGC holder graded MS-64. Interesting.
YUCK! This is one of the ugliest jobs of Artificial Toning I have ever seen. I'm thinking the AT was added to hide some problems with the coin (e.g., the hit across Liberty's eyebrow and in front of her ear and some chatter on her cheek). Does anyone think this is natural toning?
Hobo, just to add on what you said, this is a dime I found in change. a 2006D Roosevelt... I doubt its natural. the colors are way too intense, especially for 2006 - heck, its not even silver! lol and Hobo, that is one of the worst AT jobs I've seen as well! that Morgan is hideous!
IMO, AT is anything you apply to the coin actively to make it tone. NT is something that happens on its own, and MNT(manipulated natural toning) is something that would happen on its own but given the catalyst of the human hand to set it all in motion
Taking pictures now of some different toned coins and I will post them shortly... The halo inside halos of different brilliant colors is not uncommon in proof sets and I have several to post... I also have an incredible 55 mint set with a brilliant blue and red cent... Toned coins are far better to my eye than white... YMMV art
Progress is slow today! Here is a link to a toned 57 mint set I just put up on fleabay... If linking your own auction is bad form, please let me know so I can chop it. thanks art edited - it is not so much bad form as it is just not allowed
There is no set, standard percentage. Some have said they won't pay extra for NT coins... but many will. It's strictly "market price" - whatever someone will pay for an unusual, distinctive, "one of a kind" coin. Sometimes "auction fever" will jump the price quite a bit. Occasionally, when I'm searching auction records to get a feel for fair market value, I'll see several $$$ values for a coin - all fairly consistent except for one high value. Often that was an NT coin which sold at significant premium. Maybe 30% - 50%.
