There is not enough of a question here for anyone to answer. Whatever you're looking at when you look at these photos is NOT something that anyone else can ascertain. What you're referring to right be obvious to you, in fact I'll bet it is. But we don't have a CHANCE of knowing what it is for you. One thing the last several months have taught me is that what beginners think is significant or interesting, and what experienced numismatists think is, bear little to no resemblance to each other.
Wow Kurt...feeling nice tonight huh?? The OP asked "What Type of Penny is this?" Actually it isn't a "penny" it is a cent. The UK and a few other countries use the penny, but in the US we use the cent. To be exact, yours is a Circulated 2017 D Lincoln Shield Cent.
Yeah, all true, but this fella's onto SOMETHING (hopefully not ON something), and I'm just curious enough to want to know what he's seeing to eschew my normal snarky path.
The more I look, the more convinced I am it's a "color" issue, but I'll wait to hear. It might be a lighting artifact I'm seeing, so I'll wait. It MIGHT not surprise you, but in my library, after numismatics, the next most voluminous subject is psychology. My politics section is small, but almost all are hand autographed. I'm up to my eyeballs into a volume that bridges psych AND numismatics, One Coin Is Never Enough by Dr. Michael S. Shutty, Jr.
You don't need to pose the same question over and over and over again. This is an open discussion and just as I can read the first time you asked, so can everyone else.

To me, a 2017 cent that is NOT in the RD range would be odd. This is an RD, but that makes it “ordinary on steroids”.
Red, red brown and brown are just descriptions of how much of the original mint color is left, they are all "normal". It is not unusual to find newer cents in circulation that are still red, as they have not had much time to tone yet.
