Posted this on the New Currency Acquisitions thread but thought I would show it here as well.
The short-lived Treasury (or Coin) Note Series of 1890 bore an elaborate back design (below) that was replaced by a much simpler style the following year. This 1890 example is considerably scarcer than its Series 1891 counterpart, which was produced in far greater numbers. It was printed in 1890 or early 1891.
This note has only two incomplete horizontal folds (not creases), no vertical folds and just light evidence of handling and paper counting. I would grade it EF-45 conservatively, with original paper.
