I presume this is a cent that is missing the copper plating. It has the silvery color of the exposed zinc core. Because of its reactive nature the zinc will easily corrode which seems to be happening.
I don't think it is worth much but an error collector would likely be interested.

If that's rust, you're looking at some kind of plating,zinc does not rust.

I have couple of 1943 post mint plated stillers and would bet my intire collection how this one is not a plated cent but a regular cent that's missing the plating coat is all ! I think it ll be the 1st coin I ll send to slab . I have other zincoln and I see what you are saying Maine , I also always though zinc just don't rust at all but I worked in the automobilistic factory per years and I know how any metal sheet starts to rust in a matter of hours after simply be exposed to air !

From what I've gathered, it's a penny missing the copper plating....
Sweet!
How rare are these?

Sheet metal rusts because it is made of steel....zinc is a totally different animal, it will corrode,but not rust.They make anodes from zinc for boat motors and water heaters.

What I see here is two pictures with blinding glare and a third picture with a pinkish orange tint, none of which are sufficient to authenticate an unplated planchet error. A picture should be taken with a properly set white balance and a normal Zincoln should be next to the coin in question. One was posted yesterday, look at that post to see what a difference good pics can make for authentication. |

IMO, this has been plated.
rust should definitely not be on the coin.
any rusting is evidence of tampering

It could be that the copper wash used to plate this cent was contaminated with a significant amount of zinc, making it (and other that were plated at the same time) appear much lighter than normal.

I am almost certain it is not an unplated planchet, the color is just not right. As you can see from the 1943, zinc has a distinct silvery blue hue but your 2007 has a pinkish-orange color. Jbuck mentions one possibility and I have seen many Lincolns with a plating lighter in color than normal.
Another possibility is that your coin has been heated which can also impart a lighter silvery color to a normal Zincoln. What you see as "rust" would be cuprous oxide which will form as a spotty reddish compound when copper is heated.
