Hello Group My first post. New to community. Nice Coin. I haven"t purchased my first toner yet. I would like to get into collecting some. The reason I follow and read certain treads on forums is to gain some smarts. I see that there is a few questions still out there on different toners. I also see that there are two coin worlds. There is a Coin World for coin collecting and a Coin World that you are going by these rules or else. I maybe new to collecting coins once again, but It has been in my family for over 40 years. Any collectible has a value as long as it has some one to buy it. So saying a AT has no premium is not a accurate statement. There are people including myself that are into coin art. I buy some coins because of the art work. Lets say a celebrity buys a coin. Does the price of the coin increase because of the owner? The third party graders are grading a coin on their standards. Anyone that takes that standard and holds it as this is it, will always find an argument. We already see that internet sells are changing what value a coin is worth. A coin is worth what you can sell it for. There can only be guide lines. There can not be a set in stone equation for collectibles. IMO. Sorry to rant, But I can never understand why people want to try to make rules when there are no rules. Unless they are not collectors and are investors, then that is another world. Just my thoughts.

Quote: The key difference here is the kinetics of the reaction, slow kinetics equals a natural reaction while fast kinetics equals an unnatural reaction. Reaction kinetics can be sped up by heat, increasing concentration of the reactants, and the addition of catalysts. Your final product is not always the same in a fast reaction vs slow reaction... AT vs NT is not as mysterious as most make it out to be and it is certainly not just a matter of opinion. This is getting closer to what I ask for when I say "define AT/NT". Until you specify how toning is caused, either naturally or artificially, you can't sort toning into AT or NT. It's just like you can't separate Circulated from uncirculated, until we agree that if a coin shows evidence of wear, it's circulated, otherwise it is uncirculated. In ancient times, even "doctors" didn't have a real solid grasp on how babies happen. Just as today we give the benefit of the doubt to a coin that shows no evidence of wear (even if we picked it up in a parking lot), back then, a virgin was simply a woman who had not given birth. Yep, sorry to burst anyone's bubble, but the various "messiahs" who were the result of "virgin birth" were simply the first-born children of the women. Nothing to see here, folks, move along. So at least part of one definition of AT/NT has to do with the time it takes and whether the process was "helped along" by human intervention. Let's build on that, unless you have another idea. [rant]Since when does the spell check reject "uncirculated"?[/rant]

ed-
Welcome to ccf.
You're right, there are no hard and fast rules, there is nothing more than general consensus.
In 1972, tarnish (toning, whatever) was grounds for a cc dollar to get kicked from the $30 "uncirculated" coins to the $15 "mixed circ" pile.
People who got attractively toned coins busted them out of their "reject" holders post haste, and the unattractive ones got a jeweluster bath nearly as quickly.
Dealers everywhere would dip just about every toned coin, because the popular opinion was that coins with "blast white" surfaces were best. I remember a collector telling a dealer he liked a coin, and would buy it if it wasn't toned. Before the show was over, the dealer dipped the coin and sold it to a happy buyer.
Now the pendulum has swung the other way, and dealers are trying to figure out how to undip a coin, which is a lot like unfrying an egg.
Your best bet is to collect what you enjoy, without regard for what is today's "correct" way. Alternatively, you can try to second guess they way popular opinion will run.
For example, today people are spending ridiculous prices for ms68-70 coins. Maybe you should get 20-100 times as many ms64s for the same amount of money. Then when people wake up to the fact that there is no real difference between 68 and 70 except as numbers on a competitive set, you'll have a huge supply of very nice coins that are worth almost as much each as the "better" grades.
The trick is to think things through and have faith in your own thinking, instead of joining the sheep.

There's the rub. Now you have to define slow and fast. If you put a newspaper on the table in a dark room, it will take years for it to yellow. Put the same paper in direct sunlight, and it will turn brown in a week. Both are "naturally from environmental conditions". Now apply this to coins. A few minutes on the stove obviously is AT, but what about a month in an envelope that contains sulphur? Someone posted some beautiful red silver coins that resulted from them being in facial tissue for a couple years. Since it took a couple years, is that NT? If the person who discovered this deliberately wraps up a roll of ASE in individual tissues and puts them back to mature like two year old wine, is that NT, or AT toning because it was helped along? I hope you can see the problem, and why I feel there needs to be a dialog towards a universal definition.

How about home toning kits? Let's say someone deliberately sells high-sulphur envelopes and tissues, with instructions to package each coin and put it back for two years?

I would define fast as minutes to a few days while slow would be measured in months to years. I have no problem calling a coin NT when it has received a nice long slumber in a Kraft envelope. I have met a couple oldtimers that had their entire collection stored in small Kraft envelopes an even a few dealers still do it(EAC specialist Tom Reynolds come to mind).
Regarding the home toning kit, I would certainly consider it AT if someone took the envelope, soaked it in a sulfur salt solution, dried it, and added it to the kit. If someone found commercially available envelopes with a naturally high sulfur content, I would consider it NT because nothing has been manipulated outside of the norm.

Isn't splitting hares fun? Fudd would be proud.
New we have a new problem.
With the circ vs unc problem, we don't know what happened since the moment the coin left the die/mint. All we can base the decision on is what we can observe, evidence of wear.
Apply this to the toned coin, and I think you can see the problem. If you don't know whether the toning was from decades of NT in an old sulphur-containing envelope, or from a shorter period in a deliberately dosed envelope, your definition won't work.

Ahh but there is a difference  It all goes back to the reaction kinetics- a Kraft envelope will NOT tone a coin in the same manner as a coin placed in a sulfur salt soaked envelope. Yes, many collectors will not necessarily be able to tell the difference but understanding the chemistry behind the toning is key to being able to differentiate NT from AT. I do not mean to sound elitist here but some people simply cannot understand complex chemical oxidation reactions and that segment of the collector base(along with colorblind individuals) will never understand NT vs AT. It is certainly not simple stuff to digest and it does take alot of studying- both chemistry and the inspection of numerous toned coins. Weimar White's seminal book Coin Chemistry can help bridge the knowledge gap for collectors without a degree in Chemistry. I disagree with his premise that toning=damage but the author's knowledge of metallurgical chemistry far surpasses my own. For those not familiar with Weimar White, a blurb pulled from his book listing at Amazon- Quote: Weimar White is a chemist who has been able to explain scientifically, using chemical equations and experimentation, how coin surfaces oxidize to become toned. He has expressed his data and thoughts in a book format. His 30 year career studying silver chemistry for a large company plus serving as a numismatist for over 40 years, places him in a unique position of being able to address coin chemistry objectively. The Author specializes in Carson City coinage and is a member of the American Chemical Society, American Numismatic Association and the Liberty Seated Collector Club. He is a chemist with 17 patents relating to diverse chemical systems and has published in technical journals, with over a dozen scientific articles in the field of chemistry. The author has received a life membership award in the International Precious Metal Institute Inc. The one caveat I would like to add is that it can be difficult to determine NT/AT from pictures only. Nothing beats having a coin in hand and looking at it under a loupe and seeing how the colors interact with the light as the coin is rotated.

Quote: Weimar White is a chemist who has been able to explain scientifically, using chemical equations and experimentation, how coin surfaces oxidize to become toned. . This brings in another angle. I always though oxidation was a process where oxygen combined with metal, like rust Ferric/ous oxide, or aluminum oxide. I thought Jeweluster works because thiourea (sulphur) is more reactive than oxygen, thus combining with the tarnish and putting it into solution. Yet BadThad says tarnish is silver sulfate/ide oxide, if I understand correctly.

I pulled a few AU 40's and 50's Rosies last night that have some toning, some very nice. Does this affect their nuismatic valus any with the toning?

yes, but unlikely whether their numismatic value will exceed bullion value.

I just gotta say........... Reading this thread has been/is simply a pure pleasure. Learning from others, is the biggest reason I'm here. One of the things I know the "least" about, is toning. I don't own any, and I've never pursued any, nor do I still intend to. But learning from "the Masters" (as much as I can absorb anyway), is just fascinating for me. This topic is soooo over my little pointy head, that I'm just sittin' back tryin' to absorb as much as possible from such noted long-time highly respected CCF members. It would take me 37 lifetimes to learn what you guys must ponder, just over your lunch-hour !I continue to follow BadThad and Bio's comments all over the forum like they were the Gospel of Jesus ! .....  Thanks for the presentation and the opportunity to learn here Biggfredd ! .......

Quote: Were you standing at the Mint when those coins came off the presses? Nah, I didn't think so. You have no way of knowing what the previous owner(s) did to those coins and to say otherwise is completely disingenuous. Biokemist6, by the same logic, how do you know there were other chemicals on those coins? I'll tell you this much, so long as you're inquiring. I got those coins SP'ed through a dealer and promotional offering he got through PCGS. It was an offer I couldn't refuse. When I sold the coins in the SP slabs at my grades, I guaranteed they'd slab, anywhere, at the regular submissions level, all the buyer had to do was crack them out of the slabs before re-submitting. That was over a year ago, and I hadn't heard back from the buyer. Had the coins not slabbed at the regular level, I'd have expected, at least, to have been held to my guarantee. In fact, I had even guaranteed refunding the slabbing fees upon the presentation of valid invoices. The buyer had an email from me on all that. Quote: Nope, AT is a matter of chemistry- pure and simple. Certain reactions will only happen in a natural setting while other reactions can only occur when artificially induced. Target toning formed in an album over the course of years= natural. One sided circus colors from heating a coin on a hotplate= artificial. The key difference here is the kinetics of the reaction, slow kinetics equals a natural reaction while fast kinetics equals an unnatural reaction. Reaction kinetics can be sped up by heat, increasing concentration of the reactants, and the addition of catalysts. Your final product is not always the same in a fast reaction vs slow reaction- that pertains to the natural color progression mentioned BadThad mentioned and that progression is altered when the kinetics are changed dramatically. Yes, there will still be some grey areas for certain coins but AT vs NT is not as mysterious as most make it out to be and it is certainly not just a matter of opinion. You're over my head on that one, and I sincerely hope you take that as a compliment. The fact remains, however, that scientific application of the term, notwithstanding, it's a market grading standard, as applied to coins. It's as much a grading standard as the standard of circulation wear we're accustomed to applying to judge circulated coins. The difference is, the latter is an objective standard, while the former is a completely arbitrary standard. As such, pure and simple, the former can mean anything, at any given moment, anybody wants it to mean. PS: I'm not saying grading is objective--it's not, it's subjective. Neither am I saying grading standards are quantifiable--they're not. However, they're objective. As such, anybody can learn and apply them to arrive at his or her overall [subjective] grade.
