A denomination very rare in the states that could receive a rating above 60, and this one is such, with a PMG rating of 63.
It is currently 1 of the 6 highest graded pieces in the PMG tables (out of 90 pieces graded).
Noticeable freshness around the edges (boxing) and creases on the edges, or folds within the corners, but with no field bending and a visible striated texture.
A great rarity in this condition.
This is not only one of the six highest rated pieces of 50 mkp 1917, but ingeneral 1 of only 6 pieces rated above 60 by PMG!
