I need more expert advice on this. On Lincolns profile it appears his nose, lips, and forehead are doubled. These are the best shots I could get. I hope they are clear enough. On the reverse the doubling appears most prominent in the N in CENT. I need some younger more experienced eyes to help me. Then again maybe my eyes see something that's not there. I like the toning its acquired.
I agree with above assessment, almost looks like something can be seen in the lips area. It could just be MD or the photo or glare causing the look, etc. Better pictures are really needed with a clear shot of the areas you're questioning as often it's much easier to see things in hand than to try and get a photo of it. Sometimes taking the picture through a loupe can help.
