I went to Ken Potter's gallery and he has mentioned that these years have Lincoln's ear lobe doubled. There are pictures there and it states that the red areas are the doubling. I have looked at many many 1997's and 1984's and I can't see anything unusual. Anybody out there have any pictures that point this out so a relative newbe can determine if it is one or not? Also, I wonder how the ear could get doubled and nothing else on the coin is doubled? Most other coins that exhibit doubling have multiple areas that are discernable. I also have trouble with the 1994 doubled columns on the reverse (the last three). Can anybody recognize these? I sure can't. Even when he posts pictures of them, they do not look doubled. He points to areas on the stairs that are wavy. But wavy stairs are a far cry from doubled columns. Sure am glad I found this site as how would I ever get these questions answered otherwise. Much thanks to all who reply.
