Washington Quarter Error Doubled Ear Lobe New Error?

While there are doubled earlobes on quarters, this is not one of them. While the di is suffering a lot of die wear, it appears you coin is suffering from machine damage during the strike. Note how the area is question is flat and even has a lip on the lower area, it is die movement that caused that. Note around the rest of the back side of the ear you can see this also. Another clue that it is flat is in your first image you see that area as one color. That tells me that it is not rounded. Hub doubling causes the devices to form a second set of devices right next to the first set. Here is an example of the differences between machine damage - normal device - hub doubled device:

On the machine damaged/doubled example. See the light and how it turns dark on the contoured areas of the first device? Note how the areas where the arrows are point towards is just one color, no contour? That is because of the machines movement, it damaged that area, flattening, removing the normal contour that should be there. Middle image shows the normal shape of that device. The third image shows what a hub doubled example would be showing a spread between the two hubbings. Note how each are rounded/contoured is shape showing light to darkness. That is how we know they are rounded and not flat.

On your earlobe, we see the same color in the area in question, showing it is flatten because of damage during the strike. Thanks for the second image as it shows that it is flat. A real doubled earlobe will be rounded just like the 'O' on the hub doubled example on the third image on the right that I posted. Hope this helps. (your coin is not a doubled die)

On the right sides of the last two images you can see where the ear was altered and sharp edge is present. The edge on the left side shows die wear on that part of that device, the right side shows MD on that area of the lobe.

On a doubled ear, it should be raised usually as high as the ear itself:
