There is a footnote in the Scott Specialized catalogue that the Continental Bank Note Company produced a second special printing from new plates. These can be distinguished from the special printings of the National Bank Note Company by the white borders. The Continentals exist both perforated and imperforate, and were not regularly issued. There is a note visible on the photograph on the P.F. certificate for the 10c that there are two known sheets of ten.
