That is an example of Machine Doubling. How is that different than a doubled die? On a coin like yours, the coin was struck with a normal die. Then on the way away from the coin, the dies lightly move altering the coin. The areas you are looking at are where the dies altered the devices on a normal coin. This happens a lot. No a doubled die, the doubling is on the die, not created after the strike. (even though doubled dies show some Machine Doubling because of the same issue. But if your coin was a doubled die, you would expect the devices to be enlarged.

Note how much larger the devices are on the same area of the coin? Compare with the 'E' on WE on this coin and on your coin? When you look at Machine Doubling on a coin, the area affected are showing the same color because that area is now flattened. On a doubled die, you see notching/spreads on those areas. And the color goes from light to dark because the original contour of the coin is still there. Another example:

Three images. The center one is normal.
The one on the left is Machine doubled (MD).
The one in the right is a doubled die. DDO\DDR
Here is what the MD doubled example looks like on ONE:

Here is what the doubled like looks like:

When you see these side by side you can see the big difference.
