1922 Flat Plate Imperforate issues

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.

Scott 579, 2, perf. 11 x 10, plate number 14342

No plate number example is known of Scott 594, the 1¢ perf 11 coil waste issue.

 

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, occasional souvenir sheets, and the "die cutting omitted" experiment with press sheets in the early 2000's.

Scott 631, 1-1/2, plate number 18413

 

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, Scott 634 and 637, 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.

Scott 646, 2, plate number 19071, with a particularly runny overprint

Scott 646 var, 2¢ precancel, plate number 19070

 

1928 Hawaii overprints

The "Hawaii" overprints commemorate the 150th anniversary of the 1778 discovery of Hawaii by Captain Cook. Britain's Union Jack is part of the Hawaii state flag in commemoration of this event.

Scott 647, 2, plate number 18983

Scott 647 var, 2¢, dirty overprint mat, plate number 19055

1928 Canal Zone overprints

Denominations from 1/2¢ to $1.00 were overprinted for use in the Canal Zone. Two overprint types were used on flat plate issues, plus a handful of rotary press issues. See examples at the Canal Zone page.

1929 Kansas-Nebraska overprints

Denominations from 1¢ to 10¢ were overprinted for use in two states which had experienced a lot of postal robberies. The idea was to make the stolen stamps harder to re-sell in other states. It was not successful, and was not expanded to additional states. Despite the overprints, the stamps were valid for mailings throughout the United States. See examples at the Kansas-Nebraska page.
