Also note on your coin:
1. Note the devices showing die wear will always be in the direction of the closest rims. (Thus that is what your are seeing on the coins devices)
2. On a doubled die, you look at the centers of the devices to see if spread happened on a coins devices. If you look at the edges of the devices, that is where you will see die wear and
Machine Doubling. So look at the centers of the devices. (not the edges)
3. Note the year on your coin. it is one of the dies that were created with the old die setup processes. On the newer coins, they are created by the single squeeze methods. These will alter the devices (distorting them) on the newer coins. What does distortion look like?

Note the image on the left is showing
Machine Doubling. The image on the right is showing the distortion that the single squeezed doubled dies, leave on the
DDO for quarters. I liken this distortion to an over inflated bicycle tube:

Note the arrows points towards the distortion on the tube. The single squeeze doubled dies will show this on the doubled dies on the motto areas on the States and
ATB Quarters. (These are all from single squeeze dies) So the locations of the
DDO /
DDR's are more towards the centers of the designs. (information for future searches)
