Thanks for the response, but it is the zinc layer showing through. Thought it was toning as well, but further examination suggest that the copper layer is too thin in some areas, the areas within the circles. My first question really is the value.

 I have some 2009 Proof cents that are the same color, I don't like it but some collectors do.

 I know the early years of copper wash and plating had a learning curve (trial and error) so to speak. Never seen this effect on a proof as yet, which appears unique. I'll stand on the side line for a bit and see what the experts come up with.  Thanks, Doug.

I could swear it wasn't toning but I am not that versed in pennies toning. It seems more like the zinc layer coming through. Well toning it is then, thanks a lot for the quick responses. I'll chock this up to wishful thinking.

I have a 2009 cent Proof set and all four coins look that way. If it was Zinc showing through, what are the odds that I would get all four reverse designs with it in the same case?

There have been a couple of 1983 errors that are verified coppers. I think that was on business strikes though. A lot is written about them online.
I don't want to send you on a wild goose chase. If it were me and I had doubts, I'd weigh it -- just to eliminate that very rare possibility.

Ha, it just occurred to me. I guess I am slow today. The 2009 S Proof cents are Copper, not plated Zinc, so it can't be the Zinc showing through.

Strange color for toning, usually it' a rainbow, what I have seen that is.

Are you referring to the frosting/cameo on the coin?   That is pretty much the way it looked since the 1970's when all were cameo coins. I prefer the non frosted ones myself. My favorites are the early 60's proof cents. They look so sweet in a tube.

TO Coop: I am referring to the "Zinc" color or toning showing through on the cents, see photos. The reverse photo shows blotches of Copper on the Lincoln memorial pillars and steps.

I see it now. But I don't think it is a plus for the coin though. Most want shiny proofs.

According to an error coin grader at NGC, Cwb is correct (not that I didn't believe). The Error coin graders opinion is that it is toning on the Lincoln Cent. Thank you Cwb and all the rest of the post responders
