Choice Proof ( 12: 4,4,4). A beautiful example with hardly any marks. This is a Snow-9 which is associated with the Proof striking. It was graded prior to the Snow book (1992) which detailed the differences between Proof and MS strikings. This is in a first generation holder from over 30 years ago. It is in the "MS" attributed holder with the coin number #2013. If graded today, I expect this would grade PR64. It is better left in the old holder.
