I do not think that this is natural toning. Give it a soak in acetone and see what happens.

I think this is a beautiful coin due to the extreme toning on both the obverse and reverse. I believe it has full steps and a clean field. But can anyone tell me what the lines across the front indicate. Is this mint damage? Toned coins have been described as "nature's works of art," and in some cases they can command higher prices depending on the degree and eye appeal. Due to the oxidization process, over time copper naturally shifts from red to a brown color and appears this one is a bit in between. Beauty is in the eye of the beholder so to speak - there are people who love these type of toned coins, and others who dont. Seems natural to me. The steps of Monticello on a Jefferson nickel are often weakly struck on non proofs. Since 2004, NGC has used the 5-Full Steps (5FS) and 6-Full Steps (6FS) designations for qualifying Jefferson nickels. These designations are only used with MS (Mint State) Jefferson nickels. Proof coins are generally expected to have full steps. So no need to check cents for full steps. https://www.ngccoin.com/news/articl...eps-nickels/These look like long linear plating blisters. This error type occurs only on copper-plated zinc cents from 1982 to the present. We need a mike diamond coin error trained chatgpt  Edited by datadragon

This time DATA go very right. I am a guy who look for fake toning in the market, but this coin it is naturally. As I say it is transition from Red to Brown. What it is fumy is the fact this red toning is find only in the plated Zinc core cents. I have a few examples of and this red with violet toning is a beauty to the eye.

If it is actual toning, it will not be affected by acetone. Let OP give it a soak and post new pictures. Modern copper cents do not develop such colors without chemical assistance.

@ Hondo: If you has a small hole in the Cu plating the coins will be affected by acetone. Please go see the Zinc reactions to acetone.
Also my friend, to day the coins toning could be done with what is say naturally accelerated toning. this is done with the UV 240-280 nm, some filters, specific lights and dispatched heat. Instead to take normally years you achieve in a few hours. No chemical folk is involved. This was in the era of the Morgan\s toning. So it is far behind for the Silver and Gold coins and not for plated or clad coins.
Is no way to detect was accelerate or not. Just the year of the strike could be relative but also there no one can say how the coin was kept.

Silvio, zinc ions may react with impurities in acetone, but metallic zinc will not react with pure acetone without assistance.
If there is a "small hole in the Cu plating", the coin will eventually eat itself anyway unless it is hermetically sealed to exclude all oxygen and H2O from the environment.
This coin appears to have artificial toning, and you described ways of artificially accelerating the "toning" process. There was a thread a few months ago by a person who was proud of the rainbow toning they achieved on cents by application of a particular product - fortunately our wonderful moderators deleted that thread.
Personally, I find such coins unattractive and consider them to be damaged.

"Silvio, zinc ions may react with impurities in acetone, but metallic zinc will not react with pure acetone without assistance".
The Zn ions no but do not exist zinc without the protector envelope of the ZnO. this react with the acetone, become catalyst and has thermal reactions. this reaction will develop some gases (acetone gases) which go to depolarize some Zn ions. It is a funny reaction because many medical questions was answered by this reaction. Forgot to put the acetone formula : C3H6O
So calculate yourself the ZnO+C3H6O = ? you has the response. Becoming catalytic mean will be a chain of reactions. Some conditions must be present sure.
I like your approach of the science with our hobby.

My PhD involved environmental effects of heavy metals (especially Cu++ and Zn++) in aquatic environments, so I am somewhat familiar with their chemistry to say the least.
But let us not stray far from the current topic, which is the "toned" coin posted by OP. I assert that it is artificially toned and its rainbow colors would vanish after a soak in acetone.
True toning will not be affected by acetone. I would like to see the results of this test.

I want to thank all of the members who commented. I must confess I'm a bit overwhelmed. I found the coin in a random roll of pennies, so I don't know anymore about it, except I think it is attractive. I am a real novice and do not have the means to test the coin as suggested. I have never submitted a coin for grading. I do not have an ebay store, and have never sold a coin, and would not do so if I didn't think the toning was natural. For now I'll keep the coin since I think it is special. |

A1, there are a lot of zinc cents that are toned this way. Far too many to put it up to artificial toning. If you like them, save them. The cost of owning is only .01.

Excellent, I would keep it also and agree its a good find  No worries on learning to submit anything for grading, or learning to sell some coins if you desire at some point. Some people here forget that not everyone is an expert. They are just discussing that some people have created artificially toned coins, and in recent times even found ways to speed up the natural toning process which would therefore still look like normal toning but didnt take the normal amount of time. Finding normal coins like you did in a typical roll suggests strongly that it is just a normally toned coin. Its mainly finding these from sellers who may have directly or indirectly been involved with some of those things in order to make a profit, and unfortunately sometimes its hard even for the experts to tell whats 'questionable color' or not. https://www.originalskincoins.com/b...-toned-coinshttps://news.coinupdate.com/artific...ated-prices/https://news.coinupdate.com/questio...nable-color/https://news.coinupdate.com/fleetin...-crossovers/ |
