Authentic Toning or Not?

Is this toning natural or is it artificial? Thanks!

Edit- looks good to me! The more you know.

 

Natural. I've seen many an early wheat like that.

 

Is it your coin? If so, is there luster? Can’t tell from the photo but I find Lincoln Cents particularly hard to photograph.

 

Natural pretty coin

 

Copper remains a mystery to me. If it’s natural why are the colors all splotchy and random in places? Is it the alloy reacting differently to the environment? Thanks.

 

I don't see splotchy. I see a toned copper cent toning from the outside rim to the inside. It will not tone evenly.

 

I just looked up toned Lincoln registry sets... indeed looks par for the course. Some of those look way crazier than this one. Always grateful to learn something new. Thanks!

 

MA

 

Copper isn't a strong suit for me either...but I've seen coins toned as such and it's natural.

 

You're welcome.

 

Looks natural to me

 

It isn't a black and white issue and the whole AT/NT is really a spectrum. I would put this right in the middle of the spectrum near the QC/MA line as I consider it somewhat questionable, but close enough that I could see it straight grading and being deemed MA.

 

Agreed. If it was submitted multiple time, I'd expect this one to straight grade (be deemed MA) more times than not, but it is close enough (maybe 60/40 MA vs QC).

 

Looks good to me—NT, and a very attractive coin.

 

Cleaned and retoned naturally.

 

No doubt. I have copper cents that I have owned since my youth. One still looks mint struck yesterday. Others are various shades of red to brown. All stored the same..... I ran two copper water lines under my house side by side years ago. One is mostly green. The other isn’t. And I ran them the same day! Copper is a mystery!

 

The red center concerns me more than the rainbow toned periphery. It looks like MA album toning but maybe the coin was dipped before being placed in the album.

 

The coin is MA, I was just pointing out that the bright red center is more of a concern for me than peripheral toning, it makes the coin look strange. And neither would change my opinion of the market acceptability of the toning. Dipping is not considered harsh cleaning and coin albums are an acceptable storage method as long as they are stored in a properly controlled temperature. You can't judge the intent of the previous owner, therefore intent can't be used when determining the market acceptability of the toning.
