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 15 stamps. They can triple the value of the pair.
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.
