Position #1 ??

where would this "position # " be located on a stamp?
For example :

Scott #29
15¢ Large Queen
The Major Re-entry
Position #1

Is there a position #5, 7... how to??

Koala, there are usually no position numbers on stamps, although there are exceptions. But on any sheet of stamps they are numbered with imaginary numbers. The stamp in the upper left corner is always position 1 and count to the right to the end of the sheet ( pane ). Back to the left side and start the count on row 2.
Of course, in order to be able to do this one has to know how large the pane is. Does this make any sense?

Position #1 would be the top left stamp on a pane of stamps.
Position #5 would be the fifth stamp on the first row (provided that the sheet of stamps had more than 5 stamps on the row).

Generally speaking, the positions are counted from the top left, across the row, then across the second row, etc.

If the sheet or pane had 100 stamps (10 rows of 10 stamps), the left stamp on the second row would be position 11. The right stamp on the 9th row would be position 90.

The early stamps of Great Britain are virtually unique, in that the plate position was designated on the face of the stamp. On these (such as the penny black and penny red), the lower left corner of the stamp had a letter from A to T, designating the row of the plate position, and the lower right corner had a letter from A to L, designating the column of the stamp.

For most stamps, including the large queens, the plate position can be determined by matching some micro-characteristics of the engraving or corrections to the engraving to stamps or proof sheets where the positions have been previously determined. For some stamps, such as the early beavers, there was more than one plate or pane, so the position may be designated "A47," meaning position 47 from Pane A.

Hope that helps.
