Friedberg 352. 1891 $1 Treasury Note. PMG Superb Gem Uncirculated 67 EPQ. As was the trend at the time, this Series of 1891 note displays a much more open back design than the ornately printed backs seen on the Treasury Notes of the Series of 1890. It was believed that these open backed notes would deter counterfeiters by making them easier to spot. The face is much the same as the Series of 1890 notes though the 1891 examples are found only with a red scalloped Treasury Seal. This particular catalog number features the engraved signatures of Treasury officials Rosecrans and Nebeker. This exemplary specimen displays plentiful margins and essentially perfect centering. The paper is bright and wholly original. PMG has graded no examples of the catalog number finer. <em>From Currency Auctions of Americas sale of January 1992, lot 1542; Stanley Moryczs Fixed Price List of January 1993; Stanley Moryczs Fixed Price List of July 1997. </em>
