An odd combination of a weak obverse strike (which leaves some nicks that people might confuse for chatter) with a hammered reverse with a polished die. 66
I don't think the TPGs look at it like a wildcard -- they won't really factor into the grade. IMO, of course.
My understanding is that you are both right - sort of. You are correct that there is no deduction in any category for die lines per se. On the other hand, there is not way lines like that do not in some manner affect the eye appeal of the coin. The wild card is how much it affect that. To go any further than that, I would only be guessing.
A good point, that's why I said "really" rather than leaving out that adverb. My sense is, in the VAST majority of cases, die polish lines do not directly affect grade (although the underlying polishing may limit luster and therefore grade), and the TPGs tend to ignore them.
This and http://www.cointalk.com/t201912/ will be ending tonight. I am not sure just when I will get to the answers and standings.
Luster and strike are there, but just too many baddies to be called a 67 and they apparently did not down grade it due to the die lines. PCGS gave it a 66 and that looks about right to me. Scores will follow eventually.
