The Somerset House printings can be
distinguished by the upper most line
above the fringe at the lower right corner,
being thicker than other printings and
sometimes broken. In addition the
circle around the medallion often shows
damage. Lastly and most obviously the
color of the purple is much redder than
the De La Rue Printings
