Greg, that card is awesome. Pop 3 psa and pop 5 sgc. There are 8 known copies of this and you own one of them. I can see where the missing corner would bother some if this were say, a t206 Piedmont pop 2,000 (oh, and there are MANY ungraded t206s out there too) but that isn't the case here. Is it a 2? No, but who cares? Personally, I prefer rarity over condition, especially when the condition is fantastic other a missing 1/200th of the card.
Im not sure why a previous poster thinks that collectors choose not to grade NC's in particular, but I would love to hear his logic since NCs have sold at auction (and privately) for huge amounts of money. Not saying there aren't any raw out there, but I will bet there aren't many.
