Ok, This is gettin ridiculous, I expected that we'd have a winner long before now, so I am gonna give 1 last guess and one last clue to everyone. NONE of the grades have been right. Some close, but none as NGC did. Were I a YN, I would lay out the grades and see what has been guessed vs. what has not. Somewhere in there, I think it's pretty obvious. 1 MORE GUESS for everyone!!!! Man, I wanted to run a contest that would give a lot of people a chance to enter and win, I didn't expect it to go this long, I apologise. But I think the prize is worth it.
I'm not sure how I missed this contest, but here goes: Guess 1: MS65-Red Guess 2: MS64-Brown (I'm colourblind, so I can't distinguish brown from red in MS-state Lincolns )
