I saw this shortly after they came out. I had a few rolls I looked through when they were released and I saw what I thought to be
Machine Doubling in that area...so I tossed them in the spend jar. After hearing about these and then seeing some pics, I think the ones I had were the same. Luckily I had not spent them yet so I retrieved them. I'll see if I can get some pics of mine here, but it is pretty minor as far as
DDO's go. If I cannot get good ones here I will get some under the scope Tuesday at the shop and get them on here Tuesday night If I can.
It is my understanding that the "single squeeze" method of impressing the working dies that is now used was supposed to eliminate the possibility of doubling. Turns out that if the Hub is not perfectly aligned horizontally it can cause this sort of Doubling (mostly near the center of the coin) as it flattens. I think this is why you get doubled ear Lincolns, and doubled columns and knees.
