I have a 2005P Kansas State Quarter which is marked as a "Humpback" Bison in ANACS 66. I'm thinking of having either NGC or PCGS regrade it since it looks to be in excellent condition, perhaps achieving a higher grade. Does any one know if the "Humpback" attribution is available with NGC or PCGS, and if it will improve the overall value of the coin even if NGC or PCGS give it the same MS66 grade. * I should mention that the ANACS holder has seem some wear and the plastic is heavily marked in some areas.
This was the first I'd heard of that variety. It sounds rather minor. I saw some pictures of it, and I'm not impressed. I don't believe NGC or PCGS offer that attribution on the label. You could always give them a call to find out. Personally, I don't think it would be worth the $25-$35 to send it to them even if they did offer it.
