Scott 406 var, 2¢, plate number 5946 over plate number 5954.

The explanation for this is that an attempt was made to print from plate 5954, but the press was halted. Only the plate number was printed, which was apparently not noticed. New plate 5946 was then installed, and the supposedly blank sheet of paper was used to print the pane of stamps. Unique, Ex Lilly.

Experiment with perf. 11

Scott 461, 2¢, single-line watermark, flat plate printing, perforated 11, plate number 7261

Postal officials were looking for a compromise between the perf. 12, which separated too easily, and the perf. 10, which was hard to separate and often tore the stamps. Logically, 11 was the compromise, and the experiment was done on a small sample of 2¢ stamps that were distributed mostly in the Washington, DC area. It was not extended to other denominations yet due to World War I.

Perf. 11 was considered a success, at least for the "short" side of the stamps, but experiments continued for another decade before it was ultimately decided that 10-1/2 was the optimum balance between strength and separability for the "long" side perforations.

USPS kept perf. 10 for coil stamps because they needed the extra strength to prevent early separation. But 11 x 10-1/2 was the standard perforation gauge for the next 80 years, with only occasional exceptions. Scott 461 was the first step in that direction.
