Sure, give it a shot, a couple of things to look at before you decide though. It could be the picture or something else but look and see if there is a nick in the rim at 12 & 1 O'clock on the obverse, a scuff on the hair just east of the feather and on the reverse a mark just to the east of the horn. If those are present you have almost no chance of 66.
Please correct me if I'm wrong, but in the larger pictures the rim looks very weak to me. But it is a very nice coin...I would call it a 65.
WHAT? You don't collect them? Well I do and I want that one. I've got 6 sets in Whitman Classic Albums and many, many duplicates in 2x2's. So since I do collect them and you don't, you should be considerate of an old man and send it to me for my birthday. Not for several months, but an early present would be acceptable. :goofer: That is a nice looking coin.
I mean I am not really trying to finish a set right now, but I do have a lot. This is my only BU though.
