A solid line between two stamps, seen along the perforations in the middle, was the joint where two plates meet, the ink fills in the gap. They would be placed between each pane of 17 stamps. They can triple the value of the pair.
Precancels on this issue were cylinder printed, and can appear sideways as apposed to the upright version on stamps with perforations on all four sides.
Prior to this stamp coils had been issued in all manner of perforations. If the perforation was too large the stamps tore whilst separating from each other. Too small and the coils of stamps broke apart before they could be sold. The 10 perforation proved to be the ideal balance for coil stamps, and from this point on all coil stamps were issued with this perforation.
This stamp was in production all the way through to 1923, making it the most common 5¢ coil.
Earliest documented date of use, April 15th, 1919
On almost every coil, somewhere, you can find an example of a fake joint line drawn in. The line should be identical ink, spaced equally between the stamps, and square with the stamp
