The picture with the "Quality Alert" sign was for the die-hubbing press. Doubled dies are created during the hubbing process. If the hubbing process is interrupted and the die 'shifts' and then the process starts back up, it could create a doubled die. This 'error' has been verified and reproduced by the mint to create doubled dies.
This is an excerpt on how a Doubled Die was created during the single-squeeze hubbing process from Wexler's http://doubleddie.com/58222.html

"On October 1, 2009 I had the privilege of having a telephone conversation with George Shue, Senior Advisor in Manufacturing at the U.S. Mint. During this conversation the 2009-D Washington D.C. quarter with a major doubled die reverse came up. Mr. Shue noted that the Mint was aware of this doubled die error and how it occurred. This particular doubled die resulted when a hubbing press operator stopped one of the single-squeeze hubbing presses to realign the hub and die and then restarted the hubbing sequence. In the process a rotational misalignment of images resulted. Mr. Shue further noted that the Mint was able to reproduce the error in a test to see what caused the doubled image originally.

The conversation further revealed that the Mint was aware that even though it was contrary to policy, hubbing press operators were taking it upon themselves to sometimes stop the single-squeeze hubbing presses before the hubbing was completed to make adjustments, and then restarting the press to complete the hubbing. To prevent doubled dies like the major variety seen on the 2009-D Washington D.C. quarter from happening again, the Mint has installed “locks” on the hubbing presses."

I always wanted to purchase this book , and a few other books from the red book series , although I have a lot of books and I find some of the redundancies and repititions in them just ignorable . I do like the one Eisenhower test pattern with the extreme wide rim to be a piece I'd desire... If anyone finds one let me know

 

I am having trouble reading the labels on your post with the cover. Would love to know what they all are
