The American Plate Number Single Society
All sheet or pane issues have plate numbers in four corners (UL, UR, LL, LR) unless otherwise specified.
Denominations in parentheses are Forever stamps, if first class rate, or nominal rate, if service-inscribed. The first class rate changed from 46¢ to 49¢ on January 26, 2014. The 3 cent increase represents one cent for inflation, and 2 cents as a "temporary" increase that will allow USPS to recoup losses suffered during the recession. In theory, consumers were promised, the temporary 2 cent portion would be scaled back, dropped, or netted out of future rate increases. As it happens, that was the case, and the only modern first class rate drop came to pass, and the rate was dropped to 47¢ when the temporary increase expired.
Coil stamps have plate numbers at the bottom center or bottom right of single stamps and appear at the interval specified.
Plate numbers and copyright markings for self-adhesive booklet stamps or ATM panes appear on a peelable strip within the pane.

Originally, Scott did not plan to assign a catalog number since this issue does not meet their listing criteria for appropriately produced and distributed postage stamps. The souvenir sheet was never made available to the public, was printed in extremely limited quantities, and could only be purchased at many times face value as part of an expensive marketing gimmick.

Although the global airmail stamps of the last few years are intended to meet an airmail rate, they are valid for all types of mailings and there is no indication in the stamps' designs that they are primarily for airmail purposes. Therefore Scott assigns a regular catalog number rather than one with the traditional C prefix.
Hunting Permit stamps
$15 Canvasback Duck hunting permit stamp 2014-2015 (Scott RW81): P1111

USPS has stated that there will be no more denominated airmail stamps. Scott Publishing has indicated that the new global airmail stamps will be considered regular definitive stamps, not as airmail issues.
As of 2013, Official stamps have been "officially" discontinued. Government agencies will use up existing stock, then continue the conversion to forever stamps, meters and other postage payment methods.
A complete listing and valuation of plate numbers, positions and other marginal markings appears in the 2018 edition of the Hebert's Catalog of Plate Number Singles.
