Artificial Toning

AT NT toning

I agree with you all, some doctors out there are very deceptive with there methods, liquid and heat treatments will not flow well with the luster or cartwheel effect under a light source. However hydrosulphuric acid in its gascious form is what causes the toning from old albums as sulphites were used in the paper making process. If one can reproduce H2S in gascious form and treat a coin in some way, i believe it would be impossible to detect. Regardless if you find a coin attractive and you like the price, and the toning doesnt appear to be AT with some sort of heat or acid/sulphur compound buy it. Beauty is in the eye of the beholder.

I agree, and as far as H2S

is there even any paper products that have sodium sulphate in them nowadays?:rolling:

 

"Kraft wrapping paper: A paper made essentially from wood pulp produced by a modified sulfate pulping process. It is a comparatively coarse paper particularly noted for its strength, and in unbleached grades is primarily used as a wrapper or packaging material. It can be watermarked, striped, or calendered, and it has an acceptable surface for printing. Its natural unbleached color is brown but by the use of semibleached or fully bleached sulfate pulps it can be produced in lighter shades of brown, cream tints, and white. In addition to its use as a wrapping paper, it is converted into such products as: grocery bags, envelopes, gummed sealing tape, asphalted papers, multiwall sacks, tire wraps, butcher wraps, waxed paper, coated paper, as well as specialty bags and sacks."
( from http://www.afandpa.org/PaperProductsGlossary.aspx)

Also don't forget to include sulfite paper products as to toning possibilities

so how long does it take for paper bag toning to happen?
the degrees of it all the way up to rainbow toning?

 

Let me refer you to these references, as the question has no quantifying factors. Similar to someone asking me in L.A. , how long it will take them to get to London. Could be 18 hrs, or 18 yrs.depending if they were flying or riding a tricycle with a canoe on the back. There are just too many chemical reaction factors. The links are a little tough chemistry and physic wise, but they will help you understand better.

Lehigh is correct.

Even though people may have the knowledge to do this type of toning, doesn't automatically mean they will use it to defraud others. In Europe, the cleaning, toning ( replacing patina) , etc. of ancient coins has been going on for centuries. You need to know the dealer you are working with and trust them, or stay with PCGS, NCG.

People should not be condemned for having knowledge, any one who dedicates the time and effort can also obtain it, and it can be used ethically or unethically. The Genetic sequence for Polio is on the internet. Most well trained gene techs with the equipment could make and release Polio, and most under the age of 30 are not vaccinated unless by the government, and could be at fatal risk. There are thousands of labs around the world, even in unfriendly ( to USA) countries that could do this. Should the knowledge be sequestered?

There are people who tone coins. There is no harm in this unless they deliberately defraud someone else with their product, IMO.

I think most collectors would never do this or buy them. But if you want to so you can see the effects thats cool.

Some ppl like artificial toning, personally I don't but I like natural toning. The best thing you can do for yourself is to educate yourself about anything and everything that has to do with coins. Until you know better, stay away from toned coins, that would solve that issue. Oh and artificial toning is not just an American thing so please, let that buck stop elsewhere. good luck

 

This may be a stupid question but the progression of colors is yellow , magenta then cynide or yellow blue red , I 've been seeing most of the toned coins with yellow red then blue . Now magenta is blueish and cynide is reddish , right or wrong .

Hi,

Wrong, Cyan is bluish and magenta is reddish.

Jim

 

Thanks Jim , no wonder I was seeing more of this progression so it's yellow . red than blue .

Rusty, if you go to the first post in this thread, and print out the color chart ( I used photographic paper for it), it will really help with the color progressions.
