The OP coin is very nice. The thing about the toned Lincoln craze mentioned is that it is driven by specific individuals seeking specific dates that have low populations in high grade BN, which is what drives the big money offers. I think it’s still worth certifying, but I wouldn’t expect moon money offers on it. QC is always a risk but it looks pretty natural and should bring you a profit from the right buyer with a TrueView.
Yes- pop. 5 in MS66BN. One or more of those collectors probably has a 65BN in their set, so if it goes 66 it’s big money, if it gets a plus it’s a top pop.
I think it has a shot at 66. A couple dings on the reverse would prevent a + unless somehow it got a color bump.
