There is no way that is actually in your collection! It's so beautiful! You are lucky! Sorry, I'll say MS64 with NO star because it's an old holder.
Wish I could spin this coin to see if that is breaks in luster or just the way the sweet toning plays with the light. I am going to go out on a limb again and say an ultra clean AU58+
Really nice coin, I have to discard any notion of 63. There's nothing too distracting on the obverse and the toning and luster are pretty lovely. The reverse is surprisingly nice the way it's rendered here, exception of black spot, just in basic eye appeal. I have 64 that are equivalent sans toning.
I thought 64 from the first set of photos. The second set seem to show much more luster. I will stick with my original gut feeling of 64 although I wouldn't be surprised with a color bump. Wasn't this holder before the star was issued?
