2017 P Missouri Quarter MD?

[Coin5]

Just want to make sure it is MD and not a Class 6 DDR before I put this coin back into circulation. The thickness of the devices towards the rim looks suspicious...
Thanks,
Adrian

Boy that is a tough one for me.
It's hard to tell if there is some notching on the upper corners of some of the letters or if that's just the lighting and reflection.

Thanks Cliff. Good to know it's dubious for others also... Here are more pics that may help.

Added: Interesting that the problem manifests all around the coin, like if the die was expanded in a class 6 DDR. I would think MD will just create a shift in the design in one direction; but I'm just guessing and you are the ones who know what you are doing.
Also there is not only one doubling; but several are visible.

I could be wrong Adrian but I think it is just Die Deterioration Doubling (DDD) LINK (http://www.lincolncentforum.com/terminology-list-d/#Die Deterioration Doubling). It all is towards the rim of the coin which is what happens with the deterioration doubling. I have notice that the nickel based coins look and react different to this than our copper friend the Lincoln. Let's see what the more knowledgeable folks add to this.

Interesting suggestion Jon, sounds like a good candidate. I just don't have experience to tell what it is. Perhaps, it's a combo of several factors including die deterioration doubling and MD.. Maybe the more folks chime in and help with this one. Let's wait and see.
In the mean time here are more pics. These are using digital zoom which unfortunately reduces the definition of the images..

Class 6 DDRs can not happen any more. These are struck using the single squeeze method. This one is interesting though, but I would say that it is due to die deterioration.

Thank you Bob. Your input confirms Jon's suggestion about Die Deterioration Doubling, so this case is closed for me.
Thanks again for taking the time to look at this coin and share your expertise.

If memory serves me correctly on incuse items doubling will manifest itself by making the devices on the coins thinner... Check out some of the shield cents with DDRs that include EPU and you will see what it does... On VVs 2015 DDR-001 http://varietyvista.com/01e%20LC%20D...001%20cent.htm while we can only see the tops of PLURIB it does show how thin they are and the distortion... Here is CCs 2010 002 http://www.coppercoins.com/lincoln/d...&die_state=mds and the best yet 2011 002 http://www.coppercoins.com/lincoln/d...&die_state=mds Hope that helps a bit!!!
