OK Here It Is! 2020 D Double Die!

Nooooooooooooo!!! for the love of god don't tell me that lol

I see what your are looking at on the tops of AMERICA. But as mentioned, that is not a DDR. Note on the EPU, that the 'E' looks altered, but it is not a DDR, it is MD. Just like on the quarter reverses of the ATB. These incuse devices get larger on machine doubled examples, and smaller on the DDRs:
Machine Doubling on the EPU:

On the real DDR, these devices are reduced in size compared with a normal coin image:



On the outer devices on the DDR on the raised devices, there isn't just a mark on the tops of the devices that are doubled, but these raised devices are enlarged compared with a normal die:




Even the largest devices are made even larger:



What is unique so that I know that this is what happened on a DDR, all of these images are from the same coin.


So stop looking at the edges of the devices. The hub doubling on these enlarge the centers of the devices. Machine Doubling is found on the outside edges of devices.

Well when I first noticed the Raised and Incuse devices having opposite results, it was on this coin, (2013 DDR) that I figured this out. It was in 2013 when a great person mailed me an extra, he had found. It was a real eye opener. I first noticed, the Incuse doubling differences, then when I looked at the raised devices on the same coin, then it all came clear to me. The raised and lower devices acted exactly opposite of the other.
Machine doubling on raised devices, reduces the size of the devices outside edge.
Machine doubling on incuse devices enlarges the side on the outside edge of the devices.

A doubled die on raised devices, enlarges the center of the devices.
A doubled die on incuse devices, reduces the size of the centers devices.

Thus when the issue of the ATB Quarters with the incuse devices. on the outer ring on the reverse, it looked so much like hub doubling, but wasn't. So it eventually clicked to me, the reason that the outer incuse devices are not a doubled die is this. The true doubled dies on the single squeeze dies, are in the central areas of the designs. Not on the outer edge devices of the design. The reason is the single squeeze dies, affect the centers, is that when the hub process begins, it make a kiss mark on the blank rod. When full pressure is applied, the hub moves to the correct position. Well that first kiss happened, is where the double die will show. In the center of the design, an incuse mark on the die, will not be flatten out again. Devices will be slightly smeared, in the center of the design, were on the outer edge of the design was corrected. The outer area will appear normal. Thus depending on that mis-alignment, of the hub and the new location, will be where the distortion point happened. Thus the extra earlobes on the obverses:

The indent into the center of the die blank, doesn't get changed, thus a raised area shows on the ear area.
On the motto, the true design is altered/distorted into a doubled die:

Also note on the normal image on the left, there is also Machine Doubling. Note how the MD reduced the size of the devices? MD always affects the outer edges of the devices.

So because of this distortion that can alter dies in different ways, Wexler has 176 different varieties on just one design on the States Minnesota quarters. A lot of different states this happened to also. But all these were occured during the creation of the die, when the hub alignment was slightly off, and when the full pressure was used, it moved into the correct location.
So sometimes it takes time for this to sink in. But when you figure it out, a light comes on.

CoopHome : How dies a class nine die, of the single squeeze doubled die process make these doubled dies?

Take your time with them. Learn them in and out so you won't sell them to cheap/or over rated.
