Red cents are the ones that are brand new and mint state. This kind of red, is a form of environmental damage. A rust that makes the coin look red. It was probably underground at some point. I had a photo of some very red ones that I dug up, but of course I can't find it. The 1964 penny in the center, and the dollar coin on the end. And the red Sacagawea.
Is that a mislabel? As the 2009 is a Native American Dollar with the 3 Sisters on the reverse. Even though it has Sac on the obverse, it's an NAD coin.
