The die for the penny black was engraved by William Wyon, and based on his Wyon City Medal of 1834 which depicted a fifteen-year-old Victoria
The colour of the impressions was a deep black, becoming less intense as the plates wore away. Although we have direct evidence that plates 1, 2, and 5 were hardened, it is certain that they were put to press, in the first instance, before hardening; and it is probable that many other plates were never hardened: hence the wear was very rapid, the increasing demand for the labels rendering it necessary to keep the presses at work day and night.
So early as the 30th May, 1840, we find Mr. Rowland Hill complaining to Messrs. Perkins and Co. of the large percentage of defective impressions then appearing, the responsibility for which the contractors declined to accept, stating that they were being called upon to supply twice as many labels in a given time as they had contracted for, and, to accomplish this, they were compelled to print from worn-out plates which ought to be discarded.
