Here are some photos of some DDOs and DDRs under my Bausch and Lomb Stereozoom 7. Here’s a 1965 Kennedy Half, DDR FS-802 Here are 2x 1967 CONECA DDO-003s, separated by the NGC photo to make distinguishing easier.
I’ll take a loupe to them shortly and see if I can still see them. These aren’t my cup of tea, but wanted to separate them from my bulk silver coins.
