As you can see by my user name, I am a newbie coin collector so I can really use your help on finding an answer on this coin. I purchased a mint set online called "Memorable US coins". The set came with this 1941-D Mercury dime. As I look at it under a microscope I noticed doubling on both obverse & reverse (please see pics). Most odd is on the reverse. 1- the O in "OF" does not connect 2- the right side seems to be missing a lot of detail on the branches. I would GREATLY appreciate some professional opinions. Thanking you in advance!!
