In articles I've read about the single press hubbing process, the mint had hoped that it would lessen the doubled die errors. According to the article, because the master working hub has to be slightly smaller than the collar when making the working dies, they found that even that slight movement caused a more prevalent outer mechanical distortion along the edge details in the hubbing process. What you are seeing is the results of this and isn't unique to any quarters or new coins with similar edge designs. I have found dozens like this coin roll hunting hundreds of dollars of quarters. I have yet to find a rotational hub doubling example since they began using this process. Bob is correct.Leave a comment:

I haven’t seen anything on this error specifically has anyone else? Is DDO an accurate description?

CONECA (pronounced: CŌ´NECA) is a national numismatic organization devoted to the education of error and variety coin collectors. CONECA focuses on many error and variety specialties, including doubled dies, Repunched mintmarks, multiple errors, clips, double strikes, off-metals and off-centers—just to name a few. In addition to its website, CONECA publishes an educational journal, The Errorscope, which is printed and mailed to members bimonthly. CONECA offers a lending library, examination, listing and attribution services; it holds annual meetings at major conventions (referred to as Errorama) around the country.
CONECA was formed through a merger of CONE and NECA in early 1983. To learn more about the fascinating HISTORY OF THE ERROR HOBBY and THE HISTORY OF CONECA, we encourage you to visit us our main site Here
