U.S. #510

1917-19 10¢ Franklin

As with several denominations in the Series of 1916-22 stamps, the 10¢ Franklin was issued in greater quantities than all previous stamps of that denomination.  There was a greater demand for stamps during World War I, including higher-denominated stamps that could be used to pay rates for overseas mail and parcels. 

Flat Plate, Perf. 11

The Bureau of Engraving and Printing continued to use the 10 gauge perforation machines on flat plate stamp sheets even after 11 perf. stamps proved successful.  In an effort to save money, they used the perf. 10 wheels until they wore out.  Beginning in early 1917, stamps produced on flat plate presses were given 11 gauge perfs.

That marked the beginning of the flat plate perforated 11 Series of 1917-19 stamps.  Perf. 12 had proven too flimsy, and perf. 10 was too difficult to separate without damaging the stamp, so perf. 11 became a satisfactory solution.
