Markings about the same on bridge of nose. On the no mint Lincoln, his nose and his back of collar markings. Be gentle.
Not really sure as the coins aren't in hand. They could be part of a design, or plating and die deterioration issues.
I’ll post a couple of more but same answer. The collar of his shirt. And bridge of nose. Just thought it was different. Dang I have been posting pretty good ones. Failed on this one. Still not perfect focus. Sorry.
The 1999 looks like a case of plating blisters on the bridge, ala, and collar. The 1999 D looks crisper in the bridge but possibly a blister or a clash. It is a late stage die so it may be damaged at that point. Pictures are still blurry so hard to confirm. But certainly something to get your attention.
