This quarter is part of a 1913 Proof set (cent through half dollar) I formed a few years ago. My friend, Tom Cauldwell, at Northeast Numismatics first saw this piece in the inventory of a untabled dealer who was walking around at at a Balitimore show.
Tom had passed on the coin because the price was too high for him to re-sell it, but the price was okay for my collecting purposes. By luck I was sitting at Tom's booth when that dealer walked by and Tom flagged him down. I bought the piece, and paid Tom a fee for letting use his table for the deal.
The coin is holdered in one of those gold shield, PCGS "snifter slabs." At first I thought that the gold shield coins might be something special because this coin was only graded PR-64 with great eye appeal. I soon found out that was not true. Some of the "snifter slabs" are down right ordinary.
As for my comment about the 1913
Liberty nickel, I am not a fan of that coin. To me it is an illegally made item that was stolen from the mint by a crooked employee. If I owned one, I sell it for the best money I could get, over a reasonable period of time, and buy some "real coins."
