Why are DDR's on the ATB Quarters, never seen on the outer ring areas? the ATB single squeeze die creation process does not create a DDR on that area. All the DDR's are seen more on the center devices of the design. So look for the DDR's in the Target areas

Why are there more coin machine doubled, than the 1969-S DDO-001 doubled die? Machine Doubling is a common striking event. a doubled die comes from a doubled die. because they caught this DDO early, there are only a few of the coins that got out in circulation

Can usually a single device be altered on a doubled die? not usually. The stronger doubled dies will show direction from hub misalignment. Not often that a single device be affected. If so it would be very minor.
http://goccf.com/t/432151#3716405

Want to find more doubled dies? learn how/what areas to look for doubled dies of the coins you are searching. spending more time on a coin will often find something that is not a doubled die. so know what to look for first! check your map to reach your destination.
http://goccf.com/t/432131#3716419

Is hub doubling in a different direction than Machine Doubling? Yes and no. (But mostly yes.) Machine Doubling often affects the verticals on the devices. doubled dies can be rotational hub doubling (class 1 doubled dies) or horizontal on the class 2 doubled dies. But on more of the nickels it is often seen in that pattern of being horizontal.
http://goccf.com/t/432127#3716432

What is the difference between the multi-hub dies and the single squeeze dies? profile of the devices. (Single squeeze cents have a lower profile) Die wear differences: single squeeeze dies are affected on the fields. On the multi-hub process, the devices are affected in the direction of the die wear pattern. (towards the rim direction)
http://goccf.com/t/432136#3716435

How can you tell if a coin was doubled struck and not transferred by a vise squeeze? devices will be equally struck in correct position and not mirrored.

What does distortion on a single squeeze die look like? Note the motto on the quarters? the movement of the hub alters the die on these devices, making them distorted
