This sort of toning is produced by exposure to unknown environmental conditions over the years. Copper can take on a wide variety of colors. Guessing most of these would not bring much of a premium.  to the CCF! Edited by Coinfrog

It's environmental toning, for sure. These coins are 95% copper, 5% tin and zinc. Copper is very chemically reactive. Could be smoke, moisture, some other exposure, or a combination.

Interesting. They would appear to have been exposed to environmental agents which interacted with the coins' copper surfaces--may have been deliberate/intentional or accidental (storage in a warm, humid setting, in close proximity to material with a high sulphur content--as an example).
There are some collectors who love toned Lincoln cents, and would be happy to pick up the 'better' examples for a bit over face value.

I may have said this to you before, but to the CCF!  Sometimes a humid environment will cause this. Do you happen to know if the coins stored near salt water or maybe in a lake area in the past? Coins that are stored for years on end should have some kind of Dehumidifier Desiccant and be temp controlled as well to preserve the original color of the metal. These are interesting, but spotty toning can by seen as a problem to some collectors. Solid colors and smooth gradient multi colors (rainbow toning) are usually considered more desirable on collectable coins.

Welcome
Toning is a controversial coin type.
Very hard to prove if it is natural or fake.
Otherwise a few of those are nice ones.

To CCF , Everyone pretty much hit it on the nose with the environment issue . I would like to know more details about that roll .Was the roll in a plastic tube or in original bank paper wrapper ? I have a feeling it was improperly stored for the whole roll to tone down like that . Again it's all about storage & the environment with any coin'(s) especially Brilliant Uncirculated ones .  |

Neglect is probably the biggest issue. If you have a BU coin you want to keep it looking that way for years on, keep in them a secure holder. Not the soft plastic flips that contaminate them with PVC damage. Not puting them into albums that turn the coins colors. But keep them in 2X2s, or hard flips or holders. Leaving them out or storing them with other contaminated coins in a jar will only allow them to be affected by their surroundings. Storing them in hard plastic tubes is a way to keep them safe. Some of the soft tubes are just as bad as the PVC flips. Keep them safe if you really want to keep them. If not spend them.

Thank you for the feedback everyone. These were kept in a plastic roll, but I cannot vouch for how they were stored. There are many other similar cent rolls without this toning, but two or three others where the whole sleeve is toned.

I'd bet moisture was involved. I agree with all of the above, but would like to add, toning is in the eye of the beholder. Officially, toning is damage. Some people love any sort of toning, others won't touch them no matter what. It must be "something" in the alloy mixture as well. I have a complete set of Canadian small cents, and I have many that are an incredible bright red colour in the BU examples from the 1980s through the 2000's. Extremely beautiful!  |

Not to change the subject here but.......... there is a 1963D DDO variety that exists. You may want to sort through them and see if by chance there may be one in there. |
