In 1916 Plate IV was discovered to have been damaged by rust. Two adjoining impressions, numbers 34 and 35, were affected. Even with cleaning, the printings were unsatisfactory and the two positions were cut out. Substitutions were inserted but were of a softer metal than the original steel. As a result, wear began to develop rapidly. By the end of the printings, both substituted impressions show considerable top and bottom wear.
Below are details from this copy of Position 35. The notches (top left) are a key feature in identification as is the 'blurred corner' at upper right.
