My Scott Specialized catalogue notes that there is a version of the stamp with the "Thin outer frame line at top, inner line missing", and then it continues with "(24143 LL 42)". I've figured out that 24143 is the plate number, but what does the "LL 42" mean? Is 42 a position on the sheet, in which case do you count over then down or down then over? And in any case, what does the "LL" indicate?
Thank you for your response. I had thought that LL might mean Lower Left, but it seemed superfluous given the position notation of "42" which is very specific. Even more confusing is that I have a full sheet, plate block number 24143, and none of the stamps are missing that inner line. "Curiouser and curiouser", said Alice.
You don't have a full sheet of the Poe stamps. A full sheet is actually 4 panes of 50 each. I would doubt anyone outside of the BEP and PS has full sheets. You actually have a full pane of the Poe stamp. Depending on where the plate number is found you could have an UR, UL, LR, or LL pane of the sheet. The listing means that only 1 stamp out of the 200 stamps printed in a full sheet has the variety.
Many collectors incorrectly use the word "sheet of stamps" when they really mean "pane of stamps". We can more easily understand this today when we think about the Press Sheets the PS is currently selling. The PS sells full press sheets of stamps. However, some dealers cut the press sheets into Panes and sell them, as does the PS at its offices.
