Surface-printed stamps to 1867; private telegraphs and railway parcel stamps
The first surface-printed 1-shilling stamp appeared in 1856. It had no corner letters in the design (SG72). It was replaced in 1862 by a modified design with small corner letters (SG90); this in turn was replaced in 1865 by a design with enlarged corner letters (SG101). In 1867, the watermark was changed from heraldic emblems to spray of rose (SG117).
At this time the primary use of 1-shilling stamps was to pay overseas postage (the first weight step to North America was still a shilling) as well as registration and late fees.
