The consolidation of the two companies in 1879 meant that Skinner was soon back in the fold of the ABNC.
In 1885, he engraved the United States' first Special Delivery stamps. He modelled the boy messenger on the stamp after his own nephew, Frederick Pauling, who would become a stamp engraver as well.
Skinner not only engraved stamps for the United States, he also engraved a good number of stamps for Canada and for some Central and South American countries.
When Charles Skinner engraved the vignette for the 1898 version of Canada's Victoria definitives, which was needed in response to complaints of the French speaking peoples and the UPU request for Arabic numerals, he made alterations to the Queen's jewellery and he enlarged the oval.
The portrait of King Edward VII on the 1903 Canada definitives, which Skinner engraved, was based on an engraving of that same portrait by J.A.C.Harrison for Perkins, Bacon Co.
