The possibility does exist that there potentially may exist a rarer stamp than U.S. Scott 596 sheet waste stamp which is a one cent green stamp that has the Stickney rotary press printing characteristic stamp design size and green color of U.S. Scott 581 and is perforated 11 x 11 like the flat plate U.S. Scott 552 stamp instead of 10 x 10. Only 13 used copies are known.
This stamp would be a variety of U.S. Scott 583 which is a two cents carmine Stickney rotary press stamp and it would have the same color and rotary press stamp design size but it would be perforated 11 x 11 like the flat plate U.S. Scott 554 stamp instead of 10 x 10. The hunt is on to see if it can be found. It is best to have a copy of 583 to compare its size to.
However, since the BEP sheet waste period may have been from 1922 to 1923, it may be possible that this stamp was not affected since it was issued in 1924. However, the coil waste period was from 1919 to 1924.
very interesting thoughts which I also had already, but without any deeper knowledge as you have. I also think it would be great for searching through our stamps if it could exist. Is this the 596A that Kiusala thought of? Clark once gave an answer here in the forum that today it is believed it can't exist. But perhaps you have good reasons to believe in it - or it's a different stamp than the 596A.
stamperix: Possibly Kiusalas 596A since Fourth Bureau Issue stamp expert Gary Griffith checks his 2 cents carmine with precancels for the possibility given that these have been found with slightly earlier dates than without precancels.
Hello all. I am new to the Forum, but I have been collecting off and on for 40 years. I too have thought about the subject being presented on this thread, but in a slightly different light. I have to agree with jogil that there may indeed be a rarer stamp than Scott #596, but I do not believe there exists a sheet stamp, perf. 11 of the 2 cent #583 variety. I believe that we need to re-examine the coil waste period. My thoughts are towards the possibility of the 4 cent Martha Washington coil #601 having some of it's coil waste perforated along the same lines as the other coil waste stamps already discovered, #578, #579, #594, #595. Keep in mind that the 4 cent Martha Washington coil was first issued on August 5, 1923, only 3 weeks after the 1 cent Franklin coil was issued!
