1922 Imperforate issues

Continuing a practice that began with the 1902-03 series, the Post Office provided imperforate sheet stamps to coil manufacturers.

Scott 576, 1-1/2, Plate number 16870 B

1922 Coil issues

The Post Office also issued its own coil stamps.  The plate numbers were trimmed away during the printing and coiling process.  Occasionally, the cutting process was sufficiently off-center that some portion of the plate number is still visible.

1927 Imperforate Harding (rotary press)

The post office issued imperforate stamps for vending machine companies.  These companies pasted them together in strips and privately perforated them (such as Schermack type III, with the oblongs), thus making coil rolls.  The coils were then used to affix the stamps by machine to business mail.  When one company ran out of the imperforate flat plate 1-1/2 Hardings (Scott 576) and requested more, the post office, which by then was no longer printing flat plate stamps, sent imperforate rotary press stamps instead, seeing no difference.  The rotary stamps were in smaller sheets, doubling the cutting and pasting work for the private company, but the gutters on the rotary press sheets threw off the perforations.  At around the same time, Pitney-Bowes was authorized to use meters.  The combination of problems and the new competition ruined the private vending and affixing industry, and imperforate stamps have not been intentionally issued since except for the Farleys and occasional souvenir sheets.  Background information courtesy of Lawrence H.

1928 "Molly Pitcher" overprint

In an effort to save money in designing and engraving, in a couple of instances the post office decided to overprint the common 2 and 5 definitives to provide a quick "commemorative" stamp.  The "Molly Pitcher" stamp was supposed to commemorate the 150th anniversary of the 1778 Revolutionary battle of Monmouth, New Jersey.
