1922 Flat Plate Imperforate issues
Continuing a practice that began with the 1902-03 series, the Post
Office provided imperforate sheet stamps to coil manufacturers.
575, 1¢ Franklin, plate number
575 var, 1¢ Franklin precancel, plate number
575 var, 1¢ Franklin, coil leader with Schermack Type III private perforations, plate number
575 var, 1¢ Franklin, Schermack Type III private perforations from pane before slicing into coil strips, plate number
576, 1-1/2¢ Harding profile, plate number
576, 1-1/2¢ Harding profile precancel, plate number
577, 2¢, plate number
577 var, 2¢ Washington, Schermack Type III private perforations from pane before slicing into coil strips, plate number
611, 2¢ Harding, plate number
Some collectors consider the 2¢ Harding as part of, or at least very closely associated with, the Fourth Bureau Series due to the design similarities and the fact that the identical portrait was used for the 1-1/2¢ denomination soon afterward.
For a special study of the 2¢ Harding varieties, check out the Harding page.
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
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. Background information courtesy of

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.
646, 2¢, plate number
19071, with a particularly runny overprint

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.

647 var, 2¢, dirty overprint mat, plate number
648, 5¢, plate number
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.
