Fr. 1603. 1928C $1 Silver Certificate. PMG Superb Gem Uncirculated 67 EPQ.A rarely seen high grade Silver Certificate note. The PMG population of notes in the Gem range is less for this 1928C type than both the 1928D and 1928E series. PMG has graded only four at this level, with none finer and to the best of our knowledge this is the first of those to ever be offered in auction. PMG Pop 4/0.
