Just thought I'd share this cool find I got recently. I pulled this what I believe to be 1964-D DDR-007 (1964D-1DR-007 on CC) and I am pretty happy with its condition! The doubling is nothing major, but is definitely noticeable with some moderate notching towards the bottom of the letters of "ONE CENT" and top of "UNITED", as well as slightly on the designer initials. The doubling can also be seen throughout the motto, but it is not as strong as the mentioned areas. I tried to photograph the doubling to the best of my ability, but it may be slightly blurry in some images.
