Don't see MD or any sign of a clash.

I agree with above, just result of circulation wear.

Basically circulation flattening is similar to a Struck Through Grease error. The flattening moves the metal downwards to the with of the devices. The normal devices are narrow at the tops of the devices, and the grease prevents tapered part of the devices to be seen:  The difference is that the tapered area on circulation flattening is moving the upper thinned area, downwards. Thus they look as wide as the base of the devices.
 This flattening, makes you think it is wider, but it is just the base width of the devices you are seeing pressed downwards. If you were to look at a doubled die side view they could look more like this:
 The base of the devices are wider, thus they are showing spread. While the normal die coins, with circulation flattening, are not showing spread, but the base width of the normal devices. As the dies continue to be used, the normal width does increase, but they tend to look more distorted: Starts to look more like this:
 The aging continues:
 And more distortion:
 And even more:

 So what am I referring to as distiortion? Note on these the devices closer to the rim are wider/taller and the bottoms of the same devices. This distortion makes some dates to look like circles. Along with the distiortion you will see flow lines. Spread is not this distortion. The spread is seen on the first doubled die forward till they are noticed, or retired. The hub doubling looks like the hub itself altering the devices:

 The spread looks like the shape of the hub but wider.
 Note how the spread is seen on the centers of the devices:
 Note the spread on this die is vertical, making the tops/bottoms of the devices enlarged?


 Machine Doubling and circulation flattening alter the vertical devices most of the time.
 Note the contour is removed from one side of the devices, making the devices smaller:


 Spread can also be tripled:

 Or even Quadrupled
 On these not all areas will show the triple/quad, but the on some areas it is seen because of the hub process was slightly different.So what have we covered here. 1. That a Grease Fill and a circulation flattening widens the devices on the centers but only to the edge of the normal base of the devices. 2. On a doubled die, the hub enlarges the base of the devices in a direction. Taller/wider, but not distorted. It still maintains the shape of the hub. (On the single squeeze dies, we do see distortion of the devices because of the movement of the hub. But all the coins will show the same spread on the devices) 3. Extreme die wear will distort the devices wider than normal, but they design is also distorted. Wider at the tops/bottoms of devices closer to the rims. Hope this helps a bit more. If there are more questions, add them to a new thread. That way all can see the examples on a certain coin. CoopHome: How is spread, different than a Grease Fill and circulation flattening? flattening enlarges devices and grease strikes prevent the tapered areas of the devices to appear. Die wear is distorted more towards the closest rim direction.

Seeing coins side by side help tell the story better. Then your eyes can see and you will know which is which.

Your coin for this year has only two DDO: 1. WDDO=001 on No 2 2. WDDO=002 on America and the right edge of the building. Hope help you this, your photos do not point very well.
